slowbooting/no booting

Hi all!

I´m new to this list, but not new to k12. I´m happy for that a modern ltsp 
now is developed for fedora/redhat. 

I´ve setup stable2 and it works fine until you start to installing things, 
like for Stephen Crampton

I downloaded DVD Stable 2 and booted from it.

I did "Install to Hard Drive."

After installation, I did the following to get the mouse to show up:
yum -y --enablerepo=updates-testing update xorg-x11-drv-openchrome
reboot

I followed the instructions in the "K12Linux Quick Start Guide."  The only 
difference with my system is that I am using eth1 for my ltsp network.

I booted a client (one that has worked on K12LTSP 5EL).

The cliented loaded up through initrd.ltsp  Then, I got the following 
error:

mount:: RPC: Authentication error; why = Failed (unspecified error)
nfsmount: error mounting 172.31.100.254:/opt/ltsp/i386 on /sysroot as nfs: 
Bad file descriptor 



Exactly the same happend to me, after installing freenx and freevo(I 
believe it was that, but I´ve also tampered with the network, I got 5 eth 
ports) 

One of my intentions is to develope a thin client home media server based 
on ltsp and freevo. Anyone has some comments on that?


Also, I would like to add in on the discussion of slow boot/local app´s: 

I tried to boot 100mbits clients connected after 2 switches. Didn´t work! 
They boot after 1 switch, though. 

 Gbits clients boots it without prob´s after 2 switches. All the wiring is 
cat6, and the switches are brand new gbit. This is worrying me. In a large 
setup you have to count to at least three switches between the clients and 
the server. I haven´t tried three switches yet with gbit clients. In many 
school environments you ´ll need three switches, even four, and you can 
hardly expect all clients to be gbit. Core switch(-es), floor switches, 
classroom switches

Comments?
