>Description:
Updating a large percentage of the data on a filesystem that
is running softdeps causes the filesystem to temporarily overflow.
>How-To-Repeat:
rebuild the OS on a remote machine and rdist / and
/usr to the victim machine. The filesystem code will gripe
about the fs being full and quite a few of the rsh-ed files
will be damaged. Since this can effect critical utilities not
being copied, all bets are now off.
A contributing factor is no doubt that there was not enough spare
room for a second copy of all the files.
