Omarchy

ProbeLabs65 findings · 95 requirements

A proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Original report

omarchy-snapshot create fails with - IO Error (subvolume is not a btrfs subvolume)revision 1 · captured 2026-09-28 21:24 UTC via poll

System details

Omarchy 4.0.1-1 stable

What's wrong?

On a fresh install, fresh updates running omarchy-snapshot create fails with

create IO Error (subvolume is not a btrfs subvolume)

Omarchy installed fine ( and fast BTW ) but after installing some packages, there were no snapshots to rollback to on the boot menu, so I tried to do a manual snapshot to test and saw the error.
