The core purpose of `Prepare_config()` is to prepare the config by setting
defaults where not specified. It should not be involved itself in
validation of user options.
This can be an important distinction, for instance in `clean` where we
use this function, but avoid validation to potentially allow for an option
that deletes the config, that should work even in the face of an invalid
config.

while `lb build` ran the config validation check, spotting invalid configs
and stopping with an error, the major build stages if executed directly did
not, nor did the component stages.
here we move execution of the validation function into the common init
function, with an exported variable used to indicate that validation has
been performed. thus validation is performed no matter what part of the
build system you execute, but only once.
Gbp-Dch: Short
`Init_config_data` is more suited to build scripts than here. note that
it's not used in `config` either. this deliberately does not pass along
arguments to it because `Arguments()` can only handle the basic common
options, not the `clean` set. this is somewhat confusing and causes a
pointless execution of `getopt`. furthermore the function is expanding
slightly further beyond it's original scope, with yet more change coming
that's unsuitable for `clean`, so it makes sense to avoid using the
function here just for the couple of function calls needed.
validation of the config is disabled, as it is not performed currently.
it is not clear if it should be enabled or not for `clean`. it may be
useful to not validate, if we wish to be able to provide users with an
option to be able to delete the config.

using `$VERSION` as part of the default `$LB_ISO_PREPARER` means that when
you simply run `lb config` once, this variable is stored as a part of the
string, and replaced on use, but if you run `lb config` twice, it gets
replaced with a fixed version, that is then used in all subsequent builds.
let's replace with a placeholder (`@LB_VERSION@`) that can be used both in
the default, or in user strings, and will be replaced on use only.
this means that subsequent builds will always reflect the actual version
of live-build used.
Gbp-Dch: Ignore
`DATE_UTC_OPTION` is set in `Prepare_config()` for use by scripts, even
though only a few scripts will actually use it, since it allows those
scripts to be cleaner. we may want to possibly extend this as a
`DATE_OPTIONS` variable perhaps as part of enabling proper reproduciblity.
Gbp-Dch: Short
since date is not obtained as UTC, timezone is an important detail of
understanding the given time, which users may want to make use of.
Gbp-Dch: Short
don't construct each part from a fresh "now", which can result in
inaccuracies in the overall date due to "now" drifting over the individual
date calls. instead feed the full date that was obtained back into it when
extracting the component parts.

- the definition of $PROGRAM as used in $USAGE strings defined in each
script has been broken for a long time, being simply "lb" when it needs
to be "lb COMMAND".
- `config` changed $PROGRAM to "lb config" thus its output was correct in
this regard unlike everything else, but with the switch to a more
"intelligent" `Man()` function recently, it means that instead of
`man lb config`, what was actually run was `man lb config config`,
which displayed the manpage, then on exiting with `q`, it showed some
sort of index line todo with a "config" search (no exact manpage
match?), for which you had to enter `ctrl+c` to get rid of.
this revises things to fix the issues, minimising change by changing
$PROGRAM to "lb COMMAND", with the frontend overriding this.
Gbp-Dch: Ignore
did not properly consider all usage cases properly in deciding placement.
this captured `--usage` in `$PROGRAM --usage` as the action for instance.
Gbp-Dch: Ignore
load the base set of files first, then any user arch/dist specific override
files second.
this is important since whenever config items get moved in the base files,
this can break the override files, if an option specified in one was moved
to a different common file that it loaded after.
Gbp-Dch: Ignore
these should be bypassing the possibility of running the auto script
surely, just like how this is done for `--all`, otherwise you pass through
the auto file twice.
Gbp-Dch: Ignore
- detect lack of options using actual arg count rather than first arg
being an empty string.
- fix string splitting issues by looping properly on "${@}"
- tidier

...alongside printing usage (which is perhaps unnecessary), so that it is
actually clear to users that a problem occurred, and what.
and capture it before option processing of remaining args.
Gbp-Dch: Ignore
- it's only used by the debootstrap script after alternatives were dropped
long ago, so let's move it, avoiding it being loaded for everything
else.
- there's no need to pass printing another message through it.
- there's little point in making the sid distinction if you happen to
decide to build sid, it's a given that it's less stable than stable.
really, is there any need for this at all?

the default grub config has a quirk of using the syslinux splash when
present, which as a sidenote i believe is because only the syslinux script
has the code for converting an SVG (i've not researched to confirm).
the problem is that the default splash is such, with the text listing
package versions used, that this overlaps with the menu title in grub.
i've tweaked the "built on" and package details text to reduce its size
(bumped the line-height up slightly though) to avoid the overlap.
this was a pain in the *** to get done. inkscape likes to crash at the
slightest little thing like clicking on interface controls; each time it
saves it seems to swap a bunch of stuff in the file which can make a
hugely messy diff, i had to save, close, open, change, undo, and save
again, just to get a sain diff; and numerous times testing different sizes
and such in actual builds (rather than separate conversions) some of the
package detail lines would for some unknown reason decide to end up on the
same line as another, wth...
anyway, i've finally managed to get a new revision successfully created
and it seems bug free wrt. that same line issue to me, both converting
outside of live-build (in my sid host), and within a buster build. the size
of the text changed seems closer to the size of the actual menu entries
(there's no need for it to be bigger), and now is nicely clear of the menu
title.

opening the file in inkscape resulted in a dialog explaining that inkscape
used to work on a 90 DPI basis but switched to 96 DPI for better
compatibility reasons, and wanted to convert the file.
this is simply the result of it having done the conversion.
it advised that for documents not intended to be printed that there should
be no noticeable difference. i checked the output and it seems identical
to before. i tried to look at the actual diff, but it's a lot of noise,
most of which is just reordering, and i gave up, since the output looks
identical i'm not going to worry.
Gbp-Dch: Ignore
in tweaking a previous commit to remove some excessive change before
submission, i mistakenly identified the part of the sed replacement
restored here as being unnecessary to its functionality, but in fact it is.
without it the placeholder is not actually removed.
the lack of removal of the placeholder meant that you ended up with
duplicate copies of the live menu entries.
Gbp-Dch: Ignore
more fitting now that we've moved the advanced installer entries
out to a different submenu, leaving just memtest (and HDT on
syslinux).
the advanced.cfg file is also renamed to utilities.cfg in the syslinux
case, but in a backwards compatible way of moving the user advanced.cfg
file over the new one, if the user provides a file with the old name.
alternatively we could just leave the old name in place, but that would be
a little odd.
Gbp-Dch: Short
- most entries used vga=788 rather than vga=normal (which are equivalent)
- the syslinux menu uses 788 exclusively
- so do the official install discs
Gbp-Dch: Short
This is considered to be more robust.
Two instances remain:
scripts/build/chroot_archives, line 257:
if [ "${LB_APT}" = "aptitude" ] && [ ! $(Chroot chroot "which aptitude") ]
The command is run inside a chroot where the environment might be special,
and would need further testing.
manpages/Makefile, line 42:
@if [ ! -x "$$(which po4a 2>/dev/null)" ]; \
I am insufficiently familiar with makefile syntax to edit this.
instead of cramming the live entries into a string via a layer of functions
for terminating entries with newlines, which we then have to run through
perl to tweak the newlines for correct use with sed... let's write the
entries to a temp file, then use that file in the sed replacement.
the helper functions injecting newlines to the end of entries as they were
built into a long string have obviously become unnecessary and so were
removed. one function was renamed for reasons of consistency and clarity.
the file is initially deleted before use for reasons of wanting to bullet
proof the codebase to work properly under conditions of recovering from
failure/cancellation, `--force` re-running and such.
this removes the last use of perl.

support for this has not existed since v2.0~a24-1 !!
until 4d22ca948a (v2.0~a24-1), `PROGRAM` was
defined as `PROGRAM="$(basename ${0})"`. then this commit simply got rid
of the definition.
it then flipped back and forth a bit in a few ways, but always sticking
to a simple fixed "live-build" type string after that commit, as it has
been ever since.
the code removed here has thus been junk since then, and the documentation
corrected here out of date since then.
the checking of `LB_CONFIG` is also possibly junk, but i know too little
about it. it was introduced in v1.0~a43-1 in commit
705a4178e7 with a changelog entry of
"Centraly evaluate LH_CONFIG for custom configuration file."
Gbp-Dch: Short
it reported: "possible bashism in scripts/build/binary_loopback_cfg line 284 (should be '.', not 'source')"
which is clearly a misidentification.
