Subject: setup: Use systemd sysusers mechanism to create users/groups
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1fbe95984973cdaf38ed969515d7c3b1f4c24bbd;p=people%2Fstevee%2Fipfire-3.x.git

The sysusers files will be generated by the corresponding script file,
based on the passwd and group file in the source directory.
