Sharing partitions

Hi,

I'm a relative newbie and have a newbie question. Is it possible for me to share partitions on a multi-boot system? I've got a test box with two drives, 8GB and 10GB, and I'd like to set up the second drive (8GB) with my /home, /swap and possibly /usr partitions and share them between different distros, leaving my 10GB drive for my / partitions for each distro.

Basically, I'm looking for a way to share/conserve space AND get the most distros on this box that I can. IF this is possible, I'll also want to know which partitions I can share between distros.

Much thanks to anyone with answers, regardless of which way it goes.

:study: :newbie: :cool:

I share these partitions on my quad boot
/boot
/home
/pub

I have no problems with that setup, but I'm not sure about /usr, but I think you can share it as well.

That's cool, piper, but could you explain what the /pub partition is all about? I've been advised to create the partitions as follows: /boot (100MB), /, /home and /usr and make the rest of the mountpoints/partitions subdirectories in the root directory.

Do you have any advice on how to set this up or does this method work okay?

My /pub partition is a 60 gig partition that I use for general storage, such as my urpmi stuff for Mandrake, rpms for Red Hat and source code for Gentoo along with it's portage tree. I share this partition with all my networked computers.

The way you set up your partition depends upon what your use of the computer is. See Proper Filesystem Layout for some suggestions/hints.

Extremely cool, piper! Thanks for the direction to the resources as well as an obviously working example of what's good!

I may have a new best friend...

A quick question re: one of the articles you recommended. What is a NHF? The acronym is thrown out first thing (and a couple of times) as if we (the readers of a basic explanation) should know what it means. Could you (or anyone) explain or clarify?

There are some lazy, arrogant people at justlinux.com, so the NHFs should more properly be called JustLinux help files. 'Tis a sad tale indeed.

Once upon a time, there was Sensei and he sayeth, "Let there be a linuxnewbie.org" and it was.

Sensei sayeth, "All in the community that be newbies, help other newbies out by writing Newbieized Help Files" and the community responded.

Internet.com, noticing the heavy traffic there offered Sensei many jewels and trinkets, and Sensei being a mere human, sold linuxnewbie.org. Internet.com looketh at the name and was displeased and changed both the name and the posting rules. The gurus at justlinux.com got highly peeved and abandoned that site and came here where they are allowed to help newbies freely.

Now, Linux gurus and addicts are happy hanging around here.
