Auto-install round 3 hit:
Configuring storage
Creating disklabel on /dev/vda
Creating luks on /dev/vda3
Creating lvmpv on /dev/mapper/luks-...
Creating btrfs on /dev/mapper/veilor-root
Running in cmdline mode, no interactive debugging allowed.
The exact error message is:
mount failed: wrong fs type, bad option, bad superblock on
/dev/mapper/veilor-root, missing codepage or helper program
LVM+btrfs combination causes mount failure under anaconda --cmdline.
mkfs.btrfs runs but post-create mount can't find a valid superblock.
Fix: drop LVM intermediary. Use native btrfs-on-LUKS — same pattern
Fedora KDE Spin uses by default. Cleaner, snapshot story unchanged
(btrfs subvols give us root/home split + rollback potential without
LVM's overhead).
New layout:
vda1: efi (600M)
vda2: ext4 /boot (1024M)
vda3: LUKS2 → btrfs (label=veilor)
├── subvol root → /
└── subvol home → /home
ksvalidator clean on the new template.
