 thing but I've seen posts on it. NFS likes to just drop it's

 2.6 thing. Anyone else experienced it yet?

I've had problems with the linux nfs-kernel daemon.  It would die after a few
mounts/umounts.  It worked for one user, but wouldn't do for production.  2.4
kernel.  Didn't find a solution.  However now I'm using sunos with autofs.

Question, does autofs use nfs?  On my solaris box I've defined an nfs share
with:
$ cat /etc/dfs/dfstab
share -F nfs -o rw=saraswati:parvati:lakshmi:vishnu -d home dirs /export/home

Then I setup autofs on my linux laptop and on saraswati, the sunbox.  It is
clear that I could have 'share -F autofs...', however I don't and autofs works
fine.  In partial answer to my own question, typing mount on linux reveals:
...
automount(pid2038) on /home type autofs (rw,fd=5,pgrp=2038,minproto=2,maxproto=3)
saraswati:/export/home/cory on /home/cory type nfs (rw,addr=192.168.1.5)

So I see it does use nfs.  Can anyone clear up the relation?  Why is it that
although saraswati:/export/home is mounted, only /home/cory shows up instead of
automounting the whole?  Why would I specify 'share -F autofs' as opposed to
what I have '-F nfs' ?

And finally, I also have the option of cachefs.  What is that good for?

cachefs can sit on top of/supplements nfs. In my
experience, it's most useful for slow and/or
unreliable links (similar situations web caches are
good for), though I guess there's no reason it
wouldn't work well on fast links (LAN).
