Hi,
It is generally desirable for a machine to be able to do it's basic
startup sequence even if /usr is not mounted yet (if for example it's
on a remote NFS server). This is not the case with LinuxPPC when using
DHCP to get network parameters.
Briefly, DHCP booting does not work if /usr is mounted on a remote
server. This is simply because /etc/rc.d/rc3.d/S10network uses the
'xargs' command (which is in /usr/bin instead of /bin).
(if you are wondering why somebody would do this, the idea is to
create a generic ZIP disk that can be used on any machine to start
up a full LinuxPPC session. DHCP is used so that it's not
necessary to hardwire net addresses onto the boot disk).
I believe that either xargs should not be used in startup scripts, or
xargs should be in /bin by default. After making this change, bootup
proceeds perfectly).
Just thought somebody might like to know this.
I'm not on this list--so please reply to me personally if you have
a comment.
Dave.

I am booting this way, from an MVME2306 board without harddisk.
The server providing the kernel also serves as root nfs server,
apart from /usr (due to a lack of space). The /usr fs is on
another (DEC) machine. This is no problemo at all - but I am
using BOOTP instead of DHCP (because the boards primary
bootsequence needs it).

I don't either. The /usr system is cleanly mounted while booting
the init scripts.

That would be my first thought too.
