The kernel leaves NVMe on none and everything else on mq-deadline. Neither
bounds latency once the device queue fills, so a large build, copy, or
package upgrade can make the desktop sluggish while reads wait behind a
wall of writes.
Kyber keeps separate read and sync-write queues and throttles the depth it
submits to hit a 2ms read target, which keeps interactive reads flowing
under heavy writes at negligible CPU cost. The trade is a small ceiling on
peak throughput on very fast devices, which matters for a storage server
chasing IOPS but not for a desktop.
Ships as a package-owned udev rule in /etc so it applies at boot and on
hot-plug. Existing installs pick it up at the next boot. zram is left alone
since it has nothing to schedule.

The on-battery toggle bought a fraction of a watt while the radio
idled -- twenty-some minutes across a full discharge in the best case
-- and paid for it with 20-300ms latency spikes on idle links and
outright link drops on Intel BE200/BE211 firmware. NetworkManager can
keep power save off natively with one conf.d line, which replaces the
udev rule, the setter script, and any per-card deny-listing.

Explicit profile selections from the power panel or menu are now saved
under an ac/battery key in ~/.local/state/omarchy/powerprofiles and
reapplied on boot and on plug/unplug. Only successful, user-made
selections are persisted, so the performance/balanced defaults still
apply when nothing has been chosen.
All entry points key off the same power signal, UPower's OnBattery:
the shell reads it natively and omarchy-powerprofiles-set autodetect
queries it via busctl. This replaces the sysfs online checks, which
disagreed with the shell on desktops without power_supply entries and
lagged behind plug events on some USB-C laptops.
Plug/unplug switching moves from the udev rule into the shell's battery
service, which already receives UPower's debounced state changes, so
the udev rule and its settle-sleep workaround are gone.

With a fixed --unit name, the rule fails to start when a unit from a
previous power event still exists, leaving the power profile stale.
Letting systemd-run generate unique unit names keeps every trigger
working; --collect still garbage-collects each unit on exit.

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.
