David Heinemeier HanssonandClaude Opus 5 4dcbed7728 Tune swap on zram instead of leaving it at kernel defaults
Omarchy installed zram-generator but never shipped a config for it, so the
only zram tuning any machine had was whatever the ISO wrote once, and the VM
sysctls were untouched kernel defaults aimed at spinning disks.

The generator's own default caps the device at 4G, which on a large machine
sends reclaim to the hibernation swapfile far earlier than it needs to go.
Ship min(ram / 2, 8192) instead, matching what Fedora settles on, and state
the priority explicitly since it has to sit above the pri=0 that
omarchy-hibernation-setup gives the disk swapfile.

The four sysctls follow from swap being RAM rather than a disk. swappiness
above 100 says evicting an anonymous page beats dropping a page-cache page
that would have to be read back, which is true once swap is compressed
memory. page-cluster drops to one page per fault because the default of 8
buys readahead for a seek zram doesn't have and pays a decompression for
each page. Zeroing watermark_boost_factor stops fragmentation from producing
reclaim bursts while memory is still free, and raising watermark_scale_factor
gives kswapd room to reclaim in the background instead of letting allocations
stall in direct reclaim. The last two are what actually addresses the stutter
people notice and misread as swap being used too eagerly: proactive swapping
to zram is the cure, and synchronous direct reclaim is the disease.

Every ISO-installed machine already has an unowned zram-generator.conf, which
pacman would refuse to overwrite, so both upgrade paths need it listed.

Ryan Hughes dcac0ed953 Convert plocate-ac-only, power-profile, wifi-powersave, unmount-fuse to package files
Four scripts that wrote static /etc or /usr files become package-shipped
files. The other config-script audit candidates (omarchy-ai-skill,
nautilus-python, omarchy-toggles, input-group) correctly stay scripts —
they're user-level operations, not /etc writes.

New package-owned files (omarchy-installer/etc/, shipped by
omarchy-settings):
- etc/systemd/system/plocate-updatedb.service.d/ac-only.conf
- etc/udev/rules.d/99-omarchy-power-profile.rules
- etc/udev/rules.d/99-omarchy-wifi-powersave.rules

The two udev rule files are renamed for namespacing (99-power-profile
-> 99-omarchy-power-profile; 99-wifi-powersave -> 99-omarchy-wifi-powersave)
and rewritten to invoke /usr/bin/omarchy-powerprofiles-set and
/usr/bin/omarchy-wifi-powersave instead of $HOME/.local/share/omarchy/bin/...
(both binaries ship in the omarchy package at /usr/bin/).

The battery-present gate from the original scripts is dropped — the rules
trigger on power_supply udev events, which are benign on desktops without
batteries. (The runtime commands no-op on AC-only systems.)

Script changes:
- install/config/plocate-ac-only.sh: DELETED (file ships, daemon-reload
  happens via pacman hook).
- install/config/unmount-fuse.sh: DELETED (file ships at
  /usr/lib/systemd/system-sleep/unmount-fuse via omarchy-settings).
- install/config/powerprofilesctl-rules.sh: SHRINK to runtime ops
  (enable power-profiles-daemon, udevadm reload+trigger).
- install/config/wifi-powersave-rules.sh: SHRINK to udevadm reload+trigger.
- install/config/all.sh: drop the two deleted entries.

bin/omarchy-update-system-pkgs: add --overwrite for plocate-updatedb
drop-in and unmount-fuse paths (the udev rule renames need no overwrite
since the new paths are virgin).

migrations/1779307845.sh: remove the legacy 99-power-profile.rules and
99-wifi-powersave.rules paths on existing installs, then reload udev.

Ryan Hughes e6e6328db7 Add etc/ source tree for package-shipped /etc files
This tree is the source for omarchy-settings to install into /etc
(for paths Omarchy fully owns) or stage at /usr/share/omarchy/etc-overrides
(for paths upstream packages own, which the post_install copies into place).

Package-owned drop-ins (no upstream conflict):
- etc/docker/daemon.json
- etc/systemd/system/docker.service.d/no-block-boot.conf
- etc/systemd/resolved.conf.d/20-docker-dns.conf
- etc/systemd/resolved.conf.d/10-disable-multicast.conf
- etc/systemd/system.conf.d/10-faster-shutdown.conf
- etc/systemd/system/user@.service.d/10-faster-shutdown.conf
  (renamed from .../faster-shutdown.conf for consistency)
- etc/systemd/logind.conf.d/10-ignore-power-button.conf
  (replaces the previous in-place sed-edit of logind.conf)
- etc/gnupg/dirmngr.conf
- etc/sysctl.d/99-omarchy-sysctl.conf  (renamed from the 99-sysctl.conf
  appendage; a migration cleans up the old path on existing installs)
- etc/sysctl.d/90-omarchy-file-watchers.conf
- etc/modprobe.d/omarchy-usb-autosuspend.conf
  (renamed from disable-usb-autosuspend.conf)
- etc/sudoers.d/omarchy-asdcontrol
  (renamed from asdcontrol; $USER -> %wheel for packaging)
- etc/sudoers.d/omarchy-tzupdate
- etc/sudoers.d/omarchy-passwd-tries
  (renamed from passwd-tries for namespacing)

Etc-overrides (upstream-owned paths; staged by the PKGBUILD at
/usr/share/omarchy/etc-overrides/ and cp'd in by post_install):
- etc/security/faillock.conf (owned by pam)
- etc/nsswitch.conf (owned by filesystem)
- etc/cups/cups-browsed.conf (owned by cups-browsed)
- etc/plymouth/plymouthd.conf (owned by plymouth)

All sudoers files validate with visudo -cf.

The install scripts that previously wrote these files are updated or
removed in follow-up commits.
