[K12OSN] Two subnets

Just took a look at your /etc/exports. To me, it looks fine. However,
what is interesting is that your 192.168.1.x client is looking for
/opt/ltsp/i386-1 from 192.168.0.254 instead of 192.168.1.254.
My guess is that there isn't a separate "option root-path" statement in
each "shared-network" stanza. Remember that each DHCP scope needs its
own pointer to find /opt/ltsp/<whatever>. So you want it to look sort
of like this, using my /etc/dhcpd.conf file as an example (I use
172.16.x.x networks):
shared-network WORKSTATIONS-1 {
subnet 172.16.1.0 netmask 255.255.255.0 {
range dynamic-bootp 172.16.1.100 172.16.1.253;
use-host-decl-names on;
option log-servers 172.16.1.254;
option root-path "172.16.1.254:/opt/ltsp/i386-1";
<blah blah blah>
Then, of course, you'd just comment out the global "option root-path"
statement above your "shared network" sections and bounce dhcpd. Try
that and let us know.
