nfs mount in file-system works only if "nfs4" type is used for "mount" syscall

Hello,

I ran into an issue with trying to mount an nfs file-system in an operating-system config.. I managed to trace it back to being an issue with the mount syscall.

The following did not work:

(mount "192.168.1.10:/nas-server" "/mnt/nas-client" "nfs" 0 "addr=192.168.

1.10")

and would result in an error "No route to host"

I changed the type from "nfs" to "nfs4" however and this did work (For context; at the command line, both mount.nfs and mount.nfs4 also work fine., mount.nfs also works fine without nfs-utils installed).

This might be fixable by adding another check-procedure option for "nfs4" in addition to nfs, but I am sending it your way in case there is something else going on.

Thank you!

Hello,

I ended up testing my config file with nfs4 and that part did work fine. I had earlier errors unrelated to this that threw me off thinking that would not work.

To clarify then, the issue here only seems to be with the mount function in the (guix build syscalls) module. This results in a "No route to host" error even though mount.nfs works fine on the command line.

However perhaps I am assuming that mount.nfs does not make use of nfs4 behind the scenes, even without nfs-utils installed, when it does.

Thank you!

Does this really work? I seem to recall that the bigger problem would

be that file system services do *not* and cannot currently depend on

networking (while NFS obviously does).

Here's the attached output of

$ guix system shepherd-graph gnu/system/examples/bare-bones.tmpl \

| dot -Tsvg -oout.svg

We can see that the networking service dependency chain has:

networking --> user-processes --> user-homes --> file-systems

Which to me suggests that it wouldn't be enough to fix the problem you

reported above (or perhaps it is? and NFS would simply fail during the

boot but keep trying until networking becomes available without too much

of an issue?)

Thanks,
