Subject: useradd_base.bbclass: Emulate the groupmems command using usermod
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=cec67e24ac94554e092f8ab18b42e09b4feba77e;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

useradd_base.bbclass: Emulate the groupmems command using usermod

The groupmems command does to support the --prefix option, which is
being used since commit a7b846ba7d6d63a5e59939d75d9c5fe3e4cbb0e9.
However, the groupmems command can easily be emulated using the usermod
command.
