Can tarsnap tell when it is running in a jail?  If so, maybe have it
print out one warning message when it starts up, instead of printing
one for each file where it can't read the extended attributes?  Or
maybe have a command-line option where the user can specify that they
(a) are running in a jail, or (b) don't care about saving extended
attributes?
