[->] Regardless of the opinions expressed herein by either Florian or myself,
the actual problem stum still remains: Why do I get an error regarding
*exports* of /usr, when there is no such thing being done (see very end
of this for more detail).
I would suggest removing the first of the following two lines from the
/etc/fstab.
/dev/wd0s1e /usr ufs rw 2 2
greeves:/usr /usr nfs ro 0 0
Why would you want to mount a local filesystem on the same mount point as
the network mount (without using a union/merge mount)?
[->] This is how I have mounted my /usr on the entire network: it
allows me to keep a single, updated /usr, completely superceding the
skeletal /usr that is there for booting and single user purposes.
And mounting /usr read-only is not that good, either.
[->] I disagree. A r/o /usr is a *must* when exporting it to machines
which have untrusted users with pretty much unrestricted access to their
own machines.
E.g. normally /home
is a symlink to /usr/home and therefore all your users' home directories
would be read-only. Not very nice ;)
[->] Which is why our home directories live on a separate filesystem,
/homes.
Oh, and don't forget /usr/local/etc
with a lot of the configs and the local startup stuff in rc.d/.
[->] Which is global and works just fine on every other machine which
has it mounted...
Cheers ...

Subject: Boot time message makes no sense.
Greetings!
I brought this machine up tonight, and have *never*
exported /usr, so I don't know what the following boot log
snippet is trying to tell me (first two lines to orient you
as to where in the boot sequence this occurs):
Sep 24 21:01:27 cliff /kernel: npx0 flags 0x1 on motherboard
Sep 24 21:01:28 cliff /kernel: npx0: 387 emulator
Sep 24 21:01:34 cliff mountd[99]: Can't delete exports for /usr
Here's the fstab:
# Device Mountpoint FStype Options Dump Pass#
/dev/wd0s1b none swap sw 0 0
/dev/wd0a / ufs rw 1 1
/dev/wd0s1e /usr ufs rw 2 2
/dev/wd0s1f /var/mail ufs rw 2 2
greeves:/usr /usr nfs ro 0 0
proc /proc procfs rw 0 0
and here is /etc/exports
/var/mail -maproot=0 -alldirs
Obviously we are centralizing around a new hub...
Any thoughts?
TIA,
J.Blau, Asst. Admin.
