Usage: $PROGNAME [options]
Generates a basic live ISO image of Void Linux. This ISO image can be written
to a CD/DVD-ROM or any USB stick.
To generate a more complete live ISO image, use mkiso.sh.
OPTIONS
-a <arch> Set XBPS_ARCH in the ISO image
-b <system-pkg> Set an alternative base package (default: base-system)
-r <repo> Use this XBPS repository. May be specified multiple times
-c <cachedir> Use this XBPS cache directory (default: ./xbps-cachedir-<arch>)
-k <keymap> Default keymap to use (default: us)
-l <locale> Default locale to use (default: en_US.UTF-8)
-i <lz4|gzip|bzip2|xz>
Compression type for the initramfs image (default: xz)
-s <gzip|lzo|xz> Compression type for the squashfs image (default: xz)
-o <file> Output file name for the ISO image (default: automatic)
-p "<pkg> ..." Install additional packages in the ISO image
-g "<pkg> ..." Ignore packages when building the ISO image
-I <includedir> Include directory structure under given path in the ROOTFS
-S "<service> ..." Enable services in the ISO image
-e <shell> Default shell of the root user (must be absolute path).
Set the live.shell kernel argument to change the default shell of anon.
-C "<arg> ..." Add additional kernel command line arguments
-P "<platform> ..."
Platforms to enable for aarch64 EFI ISO images (available: pinebookpro, x13s)
-T <title> Modify the bootloader title (default: Void Linux)
-v linux<version> Install a custom Linux version on ISO image (default: linux metapackage).
Also accepts linux metapackages (linux-mainline, linux-lts).
-K Do not remove builddir
-h Show this help and exit
-V Show version and exit
