If this helps any, I instrumented /etc/rc.d/rc.sysinit
and added to it to print the full fsck command being issued
and the value of the exit status of fsck.
Well, here's what my instrumentation printed:
fsck -T -t noopts=_netdev -A $fsckoptions <<<<<
rc = 16 <<<<<
return value of 16? And yet no fsck problems of any kind??
So is this an fsck bug??
Has anyone else come across this?
