‘mount -t fuse -o rw,allow_other,debug sshfs#user <at> 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 <at> 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,

T G-R

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

Then I added to ‘services’ field:
--8<---------------cut here---------------start------------->8---
    ;; 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"))
--8<---------------cut here---------------end--------------->8---
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:
--8<---------------cut here---------------start------------->8---

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,

T G-R

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