Is there any way to use this without root? about squashmount HOT 3 CLOSED

I do not think there is a reasonable way around being root for this script: After all, for executing the umount on shutdown, it is necessary to read the mounted data, and it would be a security risk to let some user write there. (Not to speak that also most mount/umount commands also require root permissions for a reason.)

What I would do in your case is to replace the first line by "#!/usr/bin/perl" (this is automatic if you install from the mv overlay) and create sudo rules by allowing
/usr/bin/squashmount stop|start [user's mountpoint]
to be executed as root by the user (with the usual restrictions of sudo of cleaning the environment etc.) without a password. Unless squashmount has a serious bug, this should be reasonably safe.

Mmm, i'm going to use a homegrown solution of unionfs-fuse (in the repos) and squashfuse. Speed is not ultra important for dosgames and there are very few writable files in games anyway and they tend to be config or saves anyway.

It's a pity that overlay requires root thou.

Since squashmount v15.0.0 there is now the possibility to use squashfuse instead of squashfs.

If combined with unionfs-fuse , adapted location for /etc/squashmount.pl and /run/squashmount, and adapted defaults for the options, it is then possible to use squashmount in user mode.

The new switch --user makes all corresponding changes ('though one can still override particular ones, of course).

Thus, I consider this bug now as closed. (I did not do too serious tests for user mode, 'though. Please open a new bug if you run into problems.)
