Edubuntu LTSP Upgrade Failure

[R. Scott Belford]

Aloha Folks

We did a system upgrade from 7.04 to 7.10 overnight.  A few things now 
fail.  Clients cannot load the kernel over nfs.  My hack to rc.local to 
allow non-clients to get a route out to the internet has stopped working.

Details as follows

hosef at liho-ltsp-g5:/etc/init.d$ ./nfs-kernel-server restart

And, in rc.local, this no longer seems to enable ip forwarding

sudo sh -c 'echo 1 > /proc/sys/net/ipv4/ip_forward'


Any suggestions are most welcome
