Ah, I see. So maybe it would be a good idea if the new fs version would
put up a big fat warning to syslog when it detects a partition written
by a previous version, telling the user that he is about to break
compatibility to his older version (and that the must upgrade userland
tools, too!)

1.0.4 . As I am now back on 2.6.11, I guess I should not upgrade to
1.0.5 or would that not do harm anyway?
