Version-stamp squashfs filename and restrict live-boot media selection
mchus released this
2026-05-04 18:44:47 +03:00 | 20 commits to main since this releaseSquashfs versioning:
- ISO now contains filesystem-v.squashfs instead of the generic
filesystem.squashfs, making it immediately visible which build is
running (visible in /run/live/medium/live/ at boot time). - Full build path: rename filesystem.squashfs → filesystem-v*.squashfs
after lb build, before lb binary_checksums/binary_iso. - Fast path: find and unpack whatever filesystem*.squashfs exists, repack
as the new versioned name, remove the old file, update the ISO. - needs_full_build: accept any filesystem*.squashfs so version changes
alone don't force a full rebuild.
Media selection hardening:
- Add live-media=/dev/disk/by-label/ to the kernel boot line in
addition to the existing live-media-label=. live-boot will now
open exactly the labeled device rather than scanning all block devices,
preventing accidental use of squashfs files from local disks or
stale virtual media attached via IPMI.
