Removing trailing slash breaks SSHFS

Removing trailing slash breaks SSHFS

[Martin Panter]

Hi

I am using the util-linux version 2.21 on Arch Linux:

https://www.archlinux.org/packages/core/x86_64/util-linux

They have patched the 2.21-6 package to include the following commit
“lib/canonicalize: always remove tailing slash”:

https://git.kernel.org/?p=utils/util-linux/util-linux.git;a=commitdiff;h=28074a0

The result of this is that my SSHFS entry in my “fstab” file no longer
works properly. To demonstrate, this “mount” command

sudo mount -t fuse 'sshfs#marty@thee:/' /media/thee

strips the trailing slash and calls

/sbin/mount.fuse sshfs#marty@thee: /media/thee -o rw

which mounts the home directory rather than the entire remote file
system. A workaround seems to be to specify a double slash (e.g.
“thee://”), but it doesn’t seem healthy and I was wondering if either
this recent slash-removal could be avoided in the “mount” command, or
if my magic SSHFS usage was abusing how “mount” is meant to work.

 use 'mount -t fuse.sshfs / /media/thee' the 'sshfs#' notation is
 deprecated.

I've reverted the patch -- the function canonicalize_path() is too
generic for such behavior.

Thanks for your bug report.
