problems when there are top level filesystem mount points
In the code that tries to mount the overlays, there is a check for top level directory mount points that is a little too aggressive for systems the have user filesystems mounted at locations like /srv and /home (which is the custom of the system administrators where I work).
this line
if [ -d "$top_dir_abs" ] && ! mountpoint -q "$top_dir_abs"; then
excludes the LVM volumes mounted at /srv/and /home on my system via the "! mountpoint" clause. When I run try from my home directory (/home/mccahill) it fails like this:
/tmp/tmp.P5nVCaSZ5L: line 4: cd: /home/mccahill: No such file or directory
Try does run correctly when run from a directory for which it has created an overlay. I can see why try wants to exclude mounts like /boot, /dev, /proc, /run, /sys, and so on, but user filesystem mounts need to have overlays.
Thanks for the report! Could you please try the branch mount-fix and let me know if it works on your setup.
I encountered this same issue, and yes the mount-fix branch fixes it for me :raised_hands:
I have the same issue, and the current main does not fix it for me:

@skorokithakis I wonder if your problem is #19. Can you show us the output of findmnt -A and lsblk?
Sure:

What happens if you try running try in temp again? Now it is failing because /home/stavros is nested.
Also, could you try with branch nested-mount (need to install mergerfs) (and running from your home dir) If you don't like mergerfs, you can install unionfs-fuse and change the two appearances of mergerfs to unionfs (L70, L83)
