* runuser: new command (derived from su(1))Karel Zak2012-09-044-8/+293
| | | | | | | | | | | | | | | | | | | | | | | This command is based on su(1), the differences: - based on Fedora runuser su(1) patch - not installed with suid rights - allowed for root users only - don't ask for password - uses PAM session, for example: $ cat /etc/pam.d/runuser auth sufficient pam_rootok.so session optional pam_keyinit.so revoke session required pam_limits.so session required pam_unix.so $ cat /etc/pam.d/runuser-l auth include runuser session optional pam_keyinit.so force revoke session include runuser Signed-off-by: Karel Zak <kzak@redhat.com>

* su: add --group and --supp-group optionsKarel Zak2012-09-042-4/+75
| | | | | | | | | | | | | | | | | | | These options allow to specify alternative groups. The command su(1) has to be executed by root. The implementation is based on Fedora runuser(1) command. For example: # su --group=kzak --supp-group=uuidd - # id uid=0(root) gid=1000(kzak) groups=0(root),985(uuidd),1000(kzak) non-root user: $ su --group=kzak - su: only root can specify alternative groups Signed-off-by: Karel Zak <kzak@redhat.com>

* vipw: make vim writebackup mode workSami Kerola2012-08-061-0/+12
| | | | | | | | | | | | Some editors, such as Vim with 'writebackup' mode enabled, use "atomic save" in which the old file is deleted and a new one with the same name created in its place. The vipw tries to detect if such happen by looking hard temporary file link count, when it is zero reopen temporary file by using it's path.
