This is however only useful when _not_ using the `u' flag. Since dump works i-node wise, the question is how to handle partial dumps if not all hard links of a file are to be backed up. This would end in a restore that could break their links. > 2. use of the old format to be able to view or restore on something other > than 4.4BSD as the dump in 4.4BSD-based system is only recoverable from > another one. What are the differences? If at all, i would argue to make this an option that's turned off by default, but so people who actually have a need for this kind of compatibility could use it. (I for myself have half a dozen or more 4.4BSD systems around, but not even a single 4.2BSD/4.3BSD derivative, so it's apparently a moot point for me. :) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
