Really not sure what makes more sense. Qemu is really slow for
non-native arches (naturally, due to the emulation.) A raspberry pi
might even be faster than that, but I don't know this for sure.

I believe GPG signing should be done on the server after uploading the
files. Transferring the general private key to your RasPi machine isn't
a good idea.

I'm also wary to having your RasPi machine log in to ymir as x2go-admin,
for that would it basically give it complete access to everything,
including git repos.

Uploading files into a staging area to which x2go-admin has access with
a new, unprivileged user and having a cron job for x2go-admin move the
files in place seems to be a saner solution.
