Somehow it is. I invoked it with: --8<---------------cut here---------------start------------->8--- $ mount -t davfs URL moint_point --8<---------------cut here---------------end--------------->8--- Looking at the whereabouts of mount: --8<---------------cut here---------------start------------->8--- mount: /run/setuid-programs/mount.davfs /run/setuid-programs/mount /run/setuid-programs/mount.ntfs-3g /run/setuid-programs/mount.nfs /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/bin/mount /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/sbin/mount.davfs /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/sbin/mount.lowntfs-3g /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/sbin/mount.ntfs /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/sbin/mount.ntfs-3g --8<---------------cut here---------------end--------------->8--- and mount.davfs: --8<---------------cut here---------------start------------->8--- mount: /run/setuid-programs/mount.davfs /run/setuid-programs/mount /run/setuid-programs/mount.ntfs-3g /run/setuid-programs/mount.nfs /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/bin/mount /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/sbin/mount.davfs /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/sbin/mount.lowntfs-3g /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/sbin/mount.ntfs /gnu/store/b01q3awvrfzaj8n8hx73qqfyf59przh8-profile/sbin/mount.ntfs-3g --8<---------------cut here---------------end--------------->8--- My $PATH: --8<---------------cut here---------------start------------->8--- /home/sstreet/.local/bin:/home/sstreet/.guix-extra-profiles/texlive/texlive/bin:/home/sstreet/.config/guix/current/bin:/home/sstreet/.guix-profile/bin:/home/sstreet/.guix-profile/sbin:/home/sstreet/.local/bin:/home/sstreet/.local/bin:/run/setuid-programs:/home/sstreet/.config/guix/current/bin:/home/sstreet/.guix-profile/bin:/home/sstreet/.guix-profile/sbin:/run/current-system/profile/bin:/run/current-system/profile/sbin --8<---------------cut here---------------end--------------->8--- It does seem that the binaries are setuid first. But then looking at my own $PATH I see the setuid paths are not first in the list. So do they have to go to the front of the list? I just tested this on a clean user account where setuid are set first, but it fails there too. I also temporarily added the mount point to /etc/fstab. Mounting this mount point as root works. It fails as user too. There is a possibility that I did not get mount flags right there, but that will be a different issue. The next will be to add this do system declaration as well.
