[systemd-devel] systemd.automount issue: Failed to initialize automounter: Operation not permitted

[Mantas Mikulėnas]

Automounts themselves are established by a magic kernel-level mount
(specifically they're "autofs" mounts), which requires root privileges.

Your systemd --user instance runs unprivileged, as your own UID, and
doesn't have the privilege to mount autofs (or anything else that isn't
FUSE).
