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.
