On ‘wand’, can you run something like:

  sudo strace -s 500 -p $(pidof sshd) -f -o sshd.log

After that, run ‘guix offload test’ from the other host, and check what
‘sshd.log’ contains.  If would in particular look for all the ‘execve’
syscalls as well as what happens right before ‘exit_group’ syscalls.
There are probably error messages lurking there.  :-)

You can share excerpts of the log but note that it will contain
sensitive crypto material, so beware.

Thanks in advance,
Ludo’.
