Installer mount target partition at /mnt. Then creates chroot environment. Mount command lists each /mnt/proc , /mnt/sys, /mnt/dev/
twice. And it is not only listing. To unbind /mnt/proc you need run this
Code:
# umount /mnt/proc
# umount /mnt/proc
umount: /mnt/proc: not mounted.
also
twice. For me something is wrong here.
Edit: setup program of installer does not provide cleanup. Running consecutively setup creates multiple binds. Maybe some make_clean script is needed. I mean before doing anything setup clears /mnt. In the last step unmounts /mnt. This way setup will be rerun in the same environment as for the very first run.
