Five-fix bundle from 7-agent research wave on the v0.5.28-final
gen_grub_cfgstub failure.
## 1. Narrow the anaconda transaction_progress patch (CRITICAL)
The v0.5.28 patch was too broad. It rewrote
`process_transaction_progress` so every 'error' token in the
transaction queue became a `log.warning`. That queue carries four
distinct error classes:
- cpio_error — payload extraction (genuinely fatal)
- script_error — RPM 6.0 cmdline-mode scriptlet warning-as-error
(the ONE we want to ignore)
- unpack_error — payload corruption (genuinely fatal)
- error — generic transaction error (genuinely fatal)
By swallowing all four we silently masked grub2-efi-x64's posttrans
failure mid-install. /boot/efi/EFI/fedora/ ended up incomplete →
gen_grub_cfgstub then failed at the bootloader install phase with
"gen_grub_cfgstub script failed" because its `set -eu` script
couldn't read the missing files.
v0.5.29 narrows the patch: override only the `script_error` callback
inside transaction_progress.py to log a warning and NOT enqueue
'error'. The consumer (`process_transaction_progress`) reverts to
upstream behaviour where cpio_error / unpack_error / error still
raise PayloadInstallationError. Real install-fatal events keep
aborting; only the F43-RPM-6.0 scriptlet regression is silenced.
The patch is applied via `python3 -c` regex rewrite (more robust
than nested sed across multi-line method bodies).
## 2. LUKS UX — `tries=5,timeout=0` (FIX)
Default cryptsetup-generator unit allows ONE passphrase try with a
1m30s wait. One typo on a long passphrase = wait 1m30s, then the
device-wait timer trips, then dracut emergency shell after 3min total.
Brutal. Adding `rd.luks.options=luks-XXX=tries=5,timeout=0` gives
five typo-friendly retries with no auto-timeout.
## 3. fbcon=nodefer on installed-system cmdline (FIX)
Live ISO cmdline already has `fbcon=nodefer` (added in v0.5.27 to fix
the real-laptop black-screen-after-dracut). The installed-system
bootloader directive in the generated install ks did NOT carry it.
Same KMS handoff happens on the installed system on the same hardware.
Now both have the flag.
## 4. /etc/crypttab fallback assertion (BELT-BRACES)
Anaconda's custom-partitioning code path normally writes /etc/crypttab
for `--encrypted` part directives. Edge cases observed in F43+ where
it doesn't. Without crypttab, systemd-cryptsetup-generator can still
work from kernel cmdline alone, but cleanup paths and second-stage
unlock both fall over. Adding a fallback `echo` that writes the
canonical line if it's missing post-anaconda.
## 5. Initramfs LUKS module assertion (DEFENSIVE)
Force-include `crypt + systemd-cryptsetup + plymouth` modules in
initramfs via /etc/dracut.conf.d/10-veilor-luks.conf. dracut autodetects
these when it sees an active LUKS mapping, but %post runs before the
LUKS state is fully observable from the chroot. Plus we wipe stale
initramfs (`rm -f /boot/initramfs-*.img`) before `--regenerate-all`
so the regen actually rewrites bytes. Final assertion runs
`lsinitrd | grep -q cryptsetup` and surfaces a [ERR] line in build
output if the module didn't make it.
## What this should fix
After the man-db fix in v0.5.28-final, install proceeded past
"Configuring xxx" cleanly but died at "Installing boot loader" with
gen_grub_cfgstub. Root-cause was the over-broad patch from #1 above.
After v0.5.29:
- Install transaction completes (man-db excluded; non-man-db
scriptlet warnings still suppressed; real errors still raise)
- gen_grub_cfgstub runs against complete /boot/efi/EFI/fedora/
- Bootloader install completes
- Reboot to disk lands at GRUB veilor-os entry
- Kernel + initramfs load (cryptsetup confirmed present)
- Plymouth LUKS prompt appears with text fallback
- User has 5 tries, no timeout
- Unlock → btrfs subvol mount → systemd → SDDM
Files: kickstart/veilor-os.ks (+45 lines), overlay/usr/local/bin/veilor-installer (+50 lines).
Verified: bash -n clean, ksvalidator clean.
