True a rom based os is a nice thing, but can you ever
change configuration files? upgrade the kernel? or what about
All these will require new card or rom upgrade from the vender
unless they give you some way to do it, possibly a flash rom
in which case someone could hack the box and possibly remotely
burn a backdoor.
IMHO a better way to do things is have the webserver nfs mount
the files from another box, which exports them read only. Then
have the nfs server locked down, even they penitrate your web server
the files are intact, which means one less thing you have to do
for damage control.
