minimise boot time in RHEL5
I work in a lab environment. We have installed RHEL5
on 20 systems. They are HP dx2480 systems. core2duo
2.9ghz cpu, 1gb ram, intel g31 mbd. All systems are networked so as to ping each other. No shares are created, neither are they registered with RHN. They take fairly long (abt 4 mts or more)time to boot to the desktop. When enabled "show details" while booting,I see that it takes quite long time at "starting e-mail services". We do not need the mail service.I need to stop it the boot process itself.
what is the file to be edited in order to do so?
Can I do it for other unrequired services as well.
