Several installer reliability fixes that were left uncommitted:
- Impermanence + multi-disk LUKS: disko-config.nix names the main LUKS
mapping `crypted` for single-disk and `crypted_main` once extraDrives is
non-empty. The impermanence rollback hook used to hardcode `crypted`,
which made every multi-disk install fail to mount root in initrd. Added
a `nomarchy.system.impermanence.mainLuksName` option and wired the
installer to write the correct value into the generated system.nix
based on the drive count.
- Password no longer cleartext in /etc/nixos: installer now hashes the
user password with `mkpasswd -m sha-512` and emits
`initialHashedPassword` instead of `initialPassword`. Added mkpasswd to
the live ISO. Cleartext is unset immediately after hashing.
USER_PASSWORD_HASH is deliberately not persisted in --resume state —
configure_user re-prompts on resume.
- Revision pinning that actually works on the live ISO: `inputs.self`
strips .git in the Nix store copy, so `git rev-parse HEAD` would silently
return empty on a real install and the generated flake would track main.
Live ISO now writes `/etc/nomarchy-rev` from `inputs.self.rev` at build
time; install.sh reads it first, falls back to git, and aborts with a
loud confirmation prompt if both are empty (instead of silently
installing an unpinned system).
- Generated `/mnt/etc/nixos/state.json`: toggle scripts (nomarchy-tz-select,
nomarchy-setup-{fido2,fingerprint}, nomarchy-toggle-hybrid-gpu,
nomarchy-wifi-powersave) `jq` this file in place and fail hard if it
doesn't exist. Fresh installs now ship a schema-conformant file matching
lib/state-schema.nix.
- Unmount /mnt before exiting `finish()` regardless of reboot choice. Clean
unmount avoids dirty BTRFS on reboot; on "no", leaving /mnt mounted
blocked a second installer run on the same live ISO.
- Removed obsolete `installer/disko-btrfs-luks.nix` (superseded by
`disko-config.nix` per commit 3aadc36) and dropped its dangling
`docs/STRUCTURE.md` reference.

- Fix critical bash dynamic scoping bug in install.sh (Impermanence/Form Factor).
- Polished Live ISO with auto-login and passwordless sudo.
- Repurposed nomarchy-toggle-suspend to directly execute systemctl suspend.
- Updated nomarchy-launch-wifi to use nmtui in alacritty.
- Optimized nomarchy-welcome to avoid redundant rebuilds via --no-update flag.
- Enabled nomarchy-welcome in Hyprland autostart.
- Wrapped Live ISO-modifying steps in welcome wizard to prevent failures.
- Removed obsolete hardware auto-detection from nomarchy-on-boot.
- Hardened script doc generator against false-positive wildcard tokens.
- Regenerated docs/SCRIPTS.md and updated docs/ROADMAP.md.
The disk phase was the dominant source of incomplete installs. Six
concrete failure modes addressed in one pass:
1. Live-ISO USB excluded from the disk picker. select_disk previously
filtered loop|ram|zram|sr but not the device the installer booted
from; picking it would format the boot media mid-install. New
detect_live_iso_devices walks /, /iso, /run/initramfs/live,
/nix/.ro-store, /nix/store and resolves each backing device to its
parent disk via lsblk -no PKNAME. Override with
NOMARCHY_INSTALL_ALLOW_ISO_TARGET=1 for the developer case.
2. 10 GiB minimum-capacity preflight. Disko fails late and obscurely
on undersized media; surface it while the picker is still open.
3. prewipe_target_drive rewritten:
- Enumerates every active dm-crypt mapping via dmsetup ls and
closes those whose backing device is on the target drive. The
old version only knew about the hardcoded names "crypted" /
"crypted_main" so an aborted multi-disk run or a non-Nomarchy
install would leave a holder open and silently break the wipe.
- Drops `|| true` from wipefs / sgdisk / dd. After the LUKS and
swap teardown above, a real failure means something is still
holding the device — surface that instead of papering over it.
- udevadm settle bounded to 30s so a flapping USB can't hang.
- Post-wipe sanity check: refuse to hand the disk to disko if
anything is still mounted off it.
4. run_disko_with_retry wraps the disko call. On failure, shows the
last 30 lines of output via gum style and offers Retry /
View full log / Abort. set -e is suspended for the disko call so
the exit code can be inspected. The previous bare `disko --mode
disko` aborted the whole installer with output scrolled past.
5. Sed-templated disko-golden.nix + disko-btrfs-multi.nix pair
replaced by a single disko-config.nix Nix function of
{ mainDrive, extraDrives ? [] } called via --argstr / --arg.
Templating Nix via shell-escaped string substitution caused at
least one production bug (3aadc36 fixed embedded-newline
escaping); function arguments are the right shape and eliminate
the entire class of escaping concerns. Single-disk path is
`extraDrives = []`; multi-disk gets BTRFS `-d single -m raid1`
plus the additional /dev/mapper/* devices. Hosts that shipped
/etc/disko-golden.nix now ship /etc/disko-config.nix.
6. EXIT trap added so the tmpfs LUKS key file (/dev/shm/nomarchy-
luks.key) is removed even if the script aborts between key-write
and the explicit unset. Replaced redundant `shred -u` on tmpfs
with `rm -f` (already in RAM).
Verification: bash -n on install.sh, nix-instantiate parse + strict
eval on disko-config.nix in both single and multi shapes, full
nix flake check --no-build evaluating all three NixOS configurations
(default, nomarchy-installer, nomarchy-live) plus the installerVm.
