No, I don't believe this! There are lots of machines around here running
with the default swap partitions mentioned in /etc/fstab. This has never
caused a problem. Surely this is standard practice? I've always done it
this way. Yes, the machines are running 4.1, and yes, I do dumps while
running multi-user. If Sun had broken this (and I guess I wouldn't be
*completely* surprised) there would have been many more people suffering
because of it.
It is kind of curious that removing the fstab line stopped the crashing
though...
