Well hopefully I'm going to get to install 4 of the distros I have (finally got a Linux rig) tomorrow afternoon/evening. I was just wondering how much room each distro needs (Ubuntu, Fedora, Debian, openSUSE)? I only have a 40gb HDD (It was a spare, had it laying around), but in reality it's only just over 38gb. So if I gave each distro a 9.5gb partition (9.5*4=38), would that be enough for a successful install for each, including updates, etc.? If not, then how much room does each distro require? Thanks.

I guess that really depends on how much you install and what distros you use. Something like DSL will only take up 50MB + swap! On the other hand a distro like Fedora may want BARE MINIMUM of 5GB + swap to work with a recommended amount of at least 10BG + swap. Same goes for ubuntu and openSuSE. As for how much swap space you use, people like to say roughly 1-1.5x your ram, but I usually just do 2GB. Maybe when I get a bigger drive i'll do more.

I wonder though, would it matter if Pyroflea were to share swap space between his many distros? Or is that not recommended? I mean, if he is only going to have one OS booted at a time I would think it would be safe, yeah?

Perfectly safe to share the swap space. I do that without any problems. I'd say that 9Gb each for the OS and 2Gb for the swap partiton would be enough. Bear in mind that you can't do this with primary partitions (only 4 per disk), so you'll need to put some of them into an extended partition. That's no problem - Linux is quite happy booting from a non-primary partition. When you've decided which distro you like, 36Gb will be more htan enough.

It should be more than enough enough for just the OS, updates, extra updates (~2GB). Remember, Linux isn't Vista =)

While that may be the case, like i said before it all depends on how many packages you install. You will save a sizeable chunk of disk space with no OO.o, but then you won't have office functionality (provided you don't install another office app or don't use google docs). The same goes for other programs as well. Back when I used fedora, it liked to install packages that did similar things, so it used a bit more space.

Anyways it is just better to allocate more space to start so you won't run into growing pains later.

I know that i'll be needing more space, but right now it's pretty much just a trial period, to see what I like and eventually eliminate it to 1 or 2 OS's on the one HDD. (would write more and explain better, but i'm on my PDA =D ).

The amount of swap you should use depends on four things:

1. How much RAM do you have?
2. Do you intend to use suspend-to-disk?
3. How much memory do you intend to use?
4. Are you running an i386/i686 distro or an amd64/x86_64 one?

- Old rule is to have 1.0-1.5x as much swap as RAM.
- If you intend to use suspend-to-disk, you must have *at least* as much swap as you do RAM, else you will not be able to suspend to disk without making some changes to s2disk and the kernel (suspending to a file rather than swap.)
- If you have a ton of RAM and don't think you'll exceed that amount, you can have a much smaller swap partition or even omit the swap.
- If you are running an i386 distro, you can't make swap partitions bigger than 2 GB.

Yes, I am actually still running the Pentium III 1.0B Coppermine in the picture.

In the, extremely unlikely, event that you need more than 2Gb of swap space you can always create multiple swap partitions. Not sure what the current limit is but it used to be 8. (I defy anyone to need more than 16Gb of swap space with a 32-bit processor!)

Hahah, knowing linux hackers, they will see that comment, and write their own custom procedure to handle more than 8 swap partitions and then create a system comprised of more swap space than system space just out of spite! ;D

True - never defy anyone to do anything! There's always some nut who'll prove you wrong.

Its just like i like to say "Every rule has an exception, even that one"
