le-os/iso

Builds the LE-OS live and installation ISO: a hybrid image that boots from CD, DVD or USB stick on UEFI and BIOS machines.

• mkleiso - the build script (run as root on LE-OS; see mkleiso --help)
• publish-iso - uploads test builds and releases to the download server
• profile/ - the release profile: package list, files overlaid on the live root, enabled services, the live initramfs configuration and the GRUB menu
• initcpio/ - the le-os-live mkinitcpio hook that finds the ISO by its label, mounts le-os/x86_64/airootfs.sfs and puts a tmpfs overlay on top

Requirements on the build host: lpm, squashfs-tools, libisoburn (xorriso), mtools, grub (with the i386-pc and x86_64-efi platforms), a signed local core repository.

./mkleiso -o ~/iso-out --gpg-key <packager key>

Publishing (publish-iso --help): every build goes to iso/testing/ first; once it has been tested, release moves it to iso/YYYY.MM.DD/, points iso/latest at it and writes the download page iso/index.html. Releases must carry a good signature by a key in the lpm keyring.

./publish-iso testing ~/iso-out/le-os-2026.11.03-x86_64.iso lpm-publish@10.10.10.95
./publish-iso release 2026.11.03 lpm-publish@10.10.10.95

Boot parameters of the live system are listed by mkinitcpio -H le-os-live.

mkleiso and the hook are adapted from Arch Linux's archiso and mkinitcpio-archiso and are licensed GPL-3.0-or-later like them (LICENSE).
