Alright, I finally got your modified file into my system declaration to
test it.  Guix has a steep learning curve, and am glad to be getting
better at hacking on it every now and then. 

Now this error message doesn't appear any more.  While entering
`mount.davfs host ~/foo`, I get a:
--8<---------------cut here---------------start------------->8---
bash: /home/ss2/.guix-profile/sbin/mount.davfs: No such file or directory
--8<---------------cut here---------------end--------------->8---
and trying it with `/run/setuid-programs/mount.davfs host ~/foo`:
--8<---------------cut here---------------start------------->8---
/run/setuid-programs/mount.davfs: no entry for /home/ss2/foo found in /etc/fstab
--8<---------------cut here---------------end--------------->8---

Which has to do with the fact that this mount does not exist in
/etf/fstab.  But so far there is no way to put an URL into system
declaration.  The manual states that there can only be a file system
label, UUID or the name of a /dev node.  So I simply tested it by
manually adding a mount to /etc/fstab, and it didn't work there either.

I'm not really sure what to do now.  Shall I post a bug report?  And if,
it may well be necessary to extend the file-systems module to
accommodate webdav mount points.  I'm not sure if it is high on anyone's
agenda, or if I could make a feature request to have this implemented.

It seems to me, that it doesn't happen that often someone would need to
mount a webdav.
