‘mount -t fuse -o rw,allow_other,debug sshfs#user@host: /mnt’ which
could be used byself or by ‘autofs’ cannot find ‘ssh’ and ‘sshfs’
binaries. A workaround are symlinks:
/bin/ssh -> /gnu/store/...-openssh-8.3p1/bin/ssh
/bin/sshfs -> /gnu/store/...-sshfs-2.10/bin/sshfs

I'm not clear on the usage of sshfs, but I just tried 'sshfs
efraim@other-machine: mnt/' and it worked without any issues.

Right. The bug is mount(8) not finding it because it(?) only
looks in /bin, apparently. This poses a problem with e.g. autofs.

However, Oleg: are you sure it looks *only* in /bin? Did you
install ‘sshfs’ to your user profile (‘guix install’ or a
manifest) or system profile (the ‘packages’ field of your
‘operating-system’)? Try the latter. See ‘Scheme Procedure:
udisks-service’ in the (guix)Desktop Services section of the
manual.

Kind regards,

I tried to install in Guix system profile via ‘packages’ field. No
success to run mount.

Then I added to ‘services’ field:
Toggle snippet (6 lines)
;; mount -t fuse and autofs
(extra-special-file "/bin/sshfs"
(file-append sshfs "/bin/sshfs"))
(extra-special-file "/bin/ssh"
(file-append openssh "/bin/ssh"))
which works without problems.

I didn't have an idea to install them in non-priveleged user profile,
because I tested with a ‘root’ account.

Here is a ‘mount -t‘ strace:

Thanks! This part comes from mount.fuse, right?

mount calls mount.fuse with $PATH unset. mount.fuse calls
<bash-minimal>/bin/sh -c sshfs …, which uses

/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:.

by default. Not very useful on Guix Systems.

I'm considering the best place to fix this: util-linux (probably),
fuse (it would only affect mount.fuse, but maybe we want that kind
of control), or bash (almost certainly not).

Kind regards,

For me, the trick was to install fuse in the system profile (to find
mount.fuse3).
