It has been observed that some chroot operations spawn additional processes which rely on chroot files. More specifically, zypper, uses gpg-agent to import and validate gpg keys for its repositories. This gpg-agent process may stay alive for longer which prevents unmounting of the tmpfs directory since the gpg-agent process still uses libraries etc which were present in the chroot. We try to solve this by using walking all the pids in /proc to find out the running processes in the chroot and kill them gracefully. If that fails for whatever reason, then we simply keep trying to umount the tmpfs directory before we give up. The gpg-agent process usually terminates soon after its home directory disappears but on fast systems we can reach the 'umount tmpfs' point before gpg-agent terminates by itself. The solution is generic enough so other 'chroot processes' can also be handled appropriately. Change-Id: Iccf332678c79266113e76f062884fc5ee79e515d |
