GSettings searches only XDG_DATA_DIRS for schemas, and none of the prefixes this unit's ExecStart searches for the binary are on it by default, so the Settings portal aborts on construction with "No such schema". Mirrors ExecStart's prefix list. Assisted-by: Claude Code:claude-opus-5 AI-Scope: Rebased onto master and reduced the explanatory comment to one line.

Summary
The Settings portal aborts on construction with "No such schema". GSettings
searches only
XDG_DATA_DIRS(plus/usr/share) for schemas, and none of theprefixes this unit's
ExecStartalready searches for the binary are on thatpath by default.
g_settings_new()on an unfound schema is a fatal error, nota catchable one, so the service fails rather than degrading.
Sets
XDG_DATA_DIRSto the same prefix listExecStartwalks, so the two stayin sync whichever one wins.
Test plan
systemd-analyze verify --useraccepts the unit, exit 0, no warnings(Debian 13 trixie, systemd 257)
/usr/shareprefix install, where the portalaborted on start and came up with this change
Not verified: I have not re-run the live portal start on a clean install since
rebasing onto current
master. The change is unit-file only, so I do notexpect that to differ, but I would rather say so than imply a fresh test.
