Could someone please test if the NBD Root boot documentation still works?

Warren


My Optiplex GX1 (PIII 450 192MB) works out of the box as a client on a fresh install of SL6.1. Even the network setup seemed to work fine for me.
When I enable NBD root instead of NFS, it gets to the login screen fine. But when I try to log in, it keeps going back to the login screen again.
Does NBD require more memory to work?

Strange... on my system, the EL6.1 chroot with NBD boot gets stuck after:
Adding udev persistent rules                                [  OK  ]

If you boot NFS the next visible thing there is starting the NBD swap,
so I tried to turn off NBD swap with no apparent effect.

I don't know what's going on.  I will dig more later.

This is with the main EL6 release. With the release 11 the NBD root works fine. So these message comparisons are between those two versions.

The only related messages in the logs are:

/var/log/secure log errors upon login attempt:
first three lines are normal for a successful login from a thin client NBD root mount.
