Since commit fdc9250bc (Changing package dependency checks within chroot
to work outside as well), Check_package automatically checks for
LB_BUILD_WITH_CHROOT and works inside as well as outside of the chroot,
so no need to check LB_BUILD_WITH_CHROOT before calling them.
Install_package and Remove_package are just a no-op when building
without chroot, so they can also be called unconditionally.
Restore_cache and Save_cache do not check LB_BUILD_WITH_CHROOT but it
it should not hurt to call them when not needed (which already happened
in some cases).
This commit makes all Check_package calls unconditional on
LB_BUILD_WITH_CHROOT.
For binary_syslinux, this fixes the check (which used outdated paths
outside the chroot since 7b6dfd9d1), for binary_grub-efi,
binary_package-lists and chroot_package-lists this simplifies the code
(but also causes the check to become package-based instead of file-based
on apt-based systems), and for binary_loadlin and binary_win32-loader
this adds the check outside the chroot which was previously missing.
Future live-build versions will still allow to use casper,
but its configuration will be done differently by a custom
config tree, rather than embedded and maintenance intensive
code in live-build itself.
Rather than a half broken image type, we'll bet our money on having proper
partman recipies support implemented for hdd image types.
Even if we don't make it for wheezy, it's better to not have virtual-hdd
in there and tell users to use the jessie version for proper hdd images.
Previously, we needed to keep the lb_* prefix as the scripts
could also be executed standalone. Since the lb wrapper is
mandatory since squeeze, we can drop this now.
