I didn't actually mean that, but put the content of the Hurd system in
the tmpfs itself.

The unionfs can however be an interesting test too.

I didn't actually mean that tmpfs has to do the untar itself, it'd be
for sure way more flexible that it's an external process just using the
tmpfs as its root FS. I don't have the time to dig more, but I guess
some statically linked tar or some such in the multiboot sequence could
manage to do the work.

Ideally, a type of archive that is able to store translators. I don't
know whether there are any. Some other way would be to just use ext2fs
and cp its content before throwing it away.

Again, I'm just thinking out loud without having the time to look at the
details, options, etc., so don't take my words for thought things.
