[Soekris] C lib update gone bad on 4526 system, boot failure

[Joshua ChaitinPollak]

Hi,

I think you are going to have to setup a DHCP/TFTP/NFS ethernet boot  
to start the board, then mount the CF's filesystem at /mnt and change  
the link back to the original libc.

The DHCP thing works roughly like this, but search for the Linux  
Diskless-HOWTO for complete information:

Find a desktop linux machine.
Plug a crossover ethernet cable between the Soekris and the Linux  
machine (or a hub and two ethernet cables)
Plug a null modem cable between the Soekris and the Linux machine
Setup a DHCP daemon, TFTP, and NFS server on the host machine
Put a PXE boot config, Linux kernel in the TFTP directory
Put a full Linux filesystem on the NFS server
Setup a console program to look at the Soekris' boot process
Boot the Soekris, when its counting down press Ctrl-P, type 'boot f0'  
and press enter
It should use DHCP, and try to boot off the network.
Then you can use the terminal program to mount the Soekris's CF and  
change the symlink.
