[SOLVED] rarfs: umount as regular user

I'm using rarfs from the AUR.  I can mount as a regular user with something like the following:

rarfs /foo/bar/file.rar /foo/bar/mnt/

However I am not able to umount as regular user with something like the following:

umount /foo/bar/mnt

I am presented with

umount: /foo/bar/mnt: umount failed: Operation not permitted

When I do an strace the last few lines are like:

mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f114aeb5000
read(3, "# Locale name alias data base.\n#"..., 4096) = 2502
read(3, "", 4096)                       = 0
close(3)                                = 0

close(2)                                = 0
exit_group(1)                           = ?
+++ exited with 1 +++

Any ideas?

Thanks

Solved with:

fusermount -u mountpoint

Re: [SOLVED] rarfs: umount as regular user

You have to be root to use umount (unless the filesystem is declared in fstab with the 'user' or 'users' options). Sounds like this is a fuse filesystem though, so just use "fusermount -u mountpoint" to unmount it.

W00t worked.  Cant believe it was that simply. 

Thanks a million!
