Subject: usermod: respect --prefix for --gid option
X-Git-Tag: 4.14.0-rc1~121
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bd2d0079c90241f24671a7946a3ad175dc1a3aeb;p=thirdparty%2Fshadow.git

usermod: respect --prefix for --gid option

The --gid option accepts a group name or id. When a name is provided, it
is resolved to an id by looking up the name in the group database
(/etc/group).

The --prefix option overides the location of the passwd and group
databases. I suspect the --gid option was overlooked when wiring up the
--prefix option.

useradd --gid already respects --prefix; this change makes usermod
behave the same way.
