piimg umount deletes several other mounts #8

Open LeBlue opened 11 years ago

LeBlue commented 11 years ago

After unmounting the Pi image I'm unable to open new gnome-terminal tab/window. It fails with:

There was an error creating the child process for this terminal, getpt failed

piimg umount seems to delete following mount, responsible for the problem: devpts on /dev/pts type devpts (rw,relatime,mode=600,ptmxmode=000)

But I think it should only unmount: devpts on /home/leblue/RPiimg/dev/pts type devpts (rw,relatime,mode=600,ptmxmode=000)

remounting devpts (mount -t devpts devpts /dev/pts) fixes above problem, but several other mounts are missing afterwards in /etc/mtab:

diff'ing my mount output before and afterwards yields the following:
