Bug#247993: sparc and silo
The install system let me create XFS partitions without warning, but
then cannot install silo because the latter doesn't support XFS. The
install system should warn people when they select filesystems that
The silo install is not idempotent: it is thus impossible to try again
without manual fiddling. The precise problem is the "ln -s . etc" and
"ln -s . boot": the install should check if these links already exist
and not fail if these are already the right ones!
