Subject: remove "." path components from required mount paths
X-Git-Tag: archive/raspbian/241-7_deb10u2+rpi1^2~47
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=e8a9a2365ee34a909ffb3875e9f073883e4f33a4;p=systemd.git

remove "." path components from required mount paths

unit_require_mounts_for may be passed path arguments that contain "."
components like for user's home directories where "." is sometimes used
to specify some form of anchor point.

This change stops considering such path as an error and removes the "."
components instead.

Closes: #11910
(cherry picked from commit 106bf8e445a797f9d9c88b827ed42193f2f6b838)
