I suggest having a separate "dar-restore-static" package for that.

Maybe you could patch it to check for ATTR support on backup at the start of
each file system. If a file system does not support ATTR then display a
single message "File system /var does not support ATTR." and continue on with
no further messages. Of course it's a bit more serious if you do a restore
with ATTR support and the file system doesn't like it...

Shouldn't be a problem, just do "ssh client restore-comand" and then the
client's stdin and stdout are the two pipes you need. Gotta test it first of
course, but I expect it to work.
