Early in the boot, mount /var/ and /tmp as tmpfs + other tweaks.
If you have no syslog (or remote syslog via tcp or udp) and just one or two deamons to run, you can get away with just a /chroot mounted tmpfs (and copy the required files in there). If your daemons don't write anything (rare - but some network daemons are like that) then you can have a fully read-only filesystem. > > ubd0*r *,this r is always won't be use ? > > What do you think would happen if you tried booting a machine with its > root filesystem on a CD-ROM? > > Jeff Using Tomcat but need to do more?
