Did you try it? I have no problems reading an AIX 3.2.5 dump tape on FreeBSD (for an example of something i've tried myself). AIX doesn't even have UFS, and it has a different byte-order. Also, DEC UNIX already offers (BSD) dump for their UFS, so having vdump more incompatible than necessary so both formats cannot be interchanged looks silly. -- 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. ;-)
