Server reboot reverts to original jumpstart configuration?

2007-12-25 0:12:00

Hello,
I have a server which when rebooted, the nsswitch.conf file come back to it
original form - not the edited version.
The server was configured with jumpstart. Some one has mention that there are
some jumpstart files left on the system which could cause this. Does anybody
know if this can be prevented or what the cause is.

The server is SUN E450 Dual CPU , Solaris 7
