Hi list,I'm trying to generate a rootfs and am using a script to add users, groups etc. I first add a group via groupadd -R ${ROOTFS_TARGET} somegroup which works fine. Using useradd with the -R parameter, to add a user also works as expected, until i try to add the -a -G somegroup options. Using usermod after creating the group and doing -a -G somegroup identically fails informing us there is no such group, somegroup.
It appears both usermod and useradd use the local /etc/group rather then what is supplied via the -R parameter. A workaround for now, is to use chroot directly, chroot ${TARGET} usermod -a -G somegroup someuser, but that only works if coreutils (or busybox (without useradd/usermod)) are already installed on the target, which may not be there (yet/at all).
Am I doing something wrong or is this indeed a bug in the coreutils?
