- Pre-activation failure ("desktop pre-activation failed"): the in-chroot
HM build hard-coded `--option substituters ""`, which only works on
OFFLINE installs (where the ISO store is copied in). Online installs
(now common — wifi works) had no pins and built from source. Fix: build
the generation in the live env (its store always has the pins), nix copy
the closure to the target, chroot only activates. In-chroot build kept
as fallback. Uses path: (not git+file:) to sidestep libgit2 ownership.
- Read-only home.nix: templates come out of the store mode 0444 and cp
preserves it — chmod -R u+w after staging so the user can edit it.
- Keyboard + locale selection: gum prompts (localectl layouts/variants +
curated UTF-8 locale list) and NOMARCHY_LOCALE/KB_LAYOUT/KB_VARIANT for
unattended. One choice flows everywhere — services.xserver.xkb (source
of truth) + console.useXkbConfig (tty/greeter) + boot.initrd.systemd
(so the LUKS passphrase prompt uses the layout; script initrd can't) +
the generated home.nix's nomarchy.keyboard.* for the Hyprland session.
- test-install.sh: NOMARCHY_OVMF env override for sandboxed OVMF paths.
Verified end-to-end in QEMU: offline LUKS install completes, boots to a
themed desktop (no autogenerated-config banner), Plymouth renders the LUKS
prompt on the theme-tinted background.

# nomarchy-install — guided installer for the Nomarchy live ISO.
|
|
#
|
|
# Partitions one disk (GPT + 1 GiB ESP + BTRFS, optional LUKS2) with disko,
|
|
# generates a downstream machine flake at /home/<user>/.nomarchy (one
|
|
# nomarchy.lib.mkFlake call — the flake the user never hand-edits), and
|
|
# runs nixos-install. Works offline: the ISO pins every flake input, and
|
|
# the target flake.lock is composed from the rev the ISO was built from.
|
|
#
|
|
# Ported from the previous iteration's installer/install.sh (3bdfc35) —
|
|
# the pre-wipe and ordering comments carry its hard-won fixes. v1 scope:
|

# single disk, UEFI only. Multi-disk RAID and impermanence live in git
|
