He's probably reluctant to teach you, because, you have to shell out a considerable amount of money to get the third-party software that makes this possible -- VMware.

Which, if you're willing to do so, would actually be a pretty good way to simultaneously boot three operating systems. VMware comes in Linux and Windows versions, and does what it says on the box; you can run an entire virtual computer inside it with it's own independent virtual hardware, at nearly native speeds. x86 only of course. I've got VMware Workstation myself, so on the rare occasions I need to boot into Windows, I can, without the risk of giving Windows full control of my computer.

If you don't want that, you'll have to triple-boot, and they won't be simultaneous.

Suppose that CentOS is the default OS, so if the user does not interact with grub, CentOS will boot automaticly. The CentOS startup scripts could fiddle with grub.conf (or use grub's saveddefault concept) so that Redhat is now the default OS. Each OS could arrange for the next OS to be the default in the same way. Now give each OS a cron job that reboots the box, say, every 2 hours. Now the box will cycle through all of the OS's in turn every 2 hours. Maybe that would be good enough.

Sweet,

If this the case, i'll try for the VMWARE software (development purposes) and see how it works. If i've trouble with it, then maybe i'll try the cron job with a cycle of 8 hours a day for each distro. (ample time download, install, push to production servers).

Thankx guys.

What I was referring to, is that he wants to run the 3 O.S.'s at the same time. Technically, you can use virtualization to do so, however, for the purpose that he wants the servers - testing patches for production- it doesn't seem like a good idea to me.

The same goes for Fedora & RedHat.

My question would be:

1. Is this possible for 3 Linux to be put in 1 box?
2. How the partitioning would be like?
3. Is there a link where i can read thru for this kind of setup?
4. Will all the OS be running simultaneously or one at a time?

Thank you in advance

Sorry man it would be risky to your drive to do all that partitioning back up the drive and yes go to www.linux.org

If your expecting it all to be all inone installation... ...it's not possible. Sorry.

Yup, i know it is risky but possible or not; that is a question that i need to anwer by do the installation first. That is what we are, system admin; to troubleshoot. Hahaha. Whatever the outcome would be, i'll post it here.
