Vagrant box creation fails: can't unmount chroot that's busy
Optimizing image for compression Umounting /tmp/tmpvsGC26 EEEK! Something bad happened... command failed: ['umount', '/tmp/tmpvsGC26'] umount: /tmp/tmpvsGC26: target is busy (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1).) Cleaning up ERROR: /tmp/tmpvsGC26: Device or resource busy rake aborted!
So I can’t build any ISO since the last changes to our build system were merged.
It’s kept busy by
/tmp/tmpvsGC26/usr/sbin/sshd. Perhaps we need to
stop the sshd service in the chroot at some point? But really, sshd
should not even start in a chroot in the first place, so apparently
something else is wrong, and it might be worth investigating to fix the
root cause of the problem instead of workaround’ing it.
