Subject: doc: clarify systemd.exec's paths definition (#3368)
X-Git-Tag: v231~239
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=043cc7151278794c4f00161b81d718f9507fdb32;p=platform%2Fupstream%2Fsystemd.git

doc: clarify systemd.exec's paths definition (#3368)

Definitions of ReadWriteDirectories=, ReadOnlyDirectories=, InaccessibleDirectories=,
WorkingDirectory=, and RootDirecory= were not clear. This patch specifies when
they are relative to the host's root directory and when they are relative to the service's
root directory.

Fixes #3248
