[lug] booting and kernel compiling (was dumpdates)

Wayde. I read this yesterday right before everything totally went hay
wire. I deleted a partition and forgot to delete it's fstab entry. And
thought my problem was that the originally Solaris disk was set to 8192
cylinders. Around the circles many times. But I also learned a lot about
disk geometry.  Funny how dumb mistakes make you smarter:}

I didn't even know the sites below existed. I'll check them out.

Boy that ain't  surprising <grin>

Ok, to be philosophical. What you're saying is that the kernel really
doesn't have anything to do with keeping the insides going, actively. I
guess that makes sense. Cron though, it get's executed something
what would that be? I assume it's fed from the internal clock (not the
bios right, bios is only the initial boot mechanism)?

The mv command doesn't even use the kernel then. Pass any arguments??

Now I get it. Thanks.

And I really appreciate all the help from you and everyone. I'd be scared
to find out how much I would have screwed up had it not been for this
group. Whoa.
