partition question

charlie_lab · 04-13-2010, 02:32 AM

Hello,

Im now trying to install LFS.
In the book there is stated that LFS works the best if you use these directory's have thier own partitions. (boot, home, usr, opt, tmp, usr/src and swap.

That are 7 partitions and I know that you can only have 4 primary partitions.

Which "must" be primary and which can be extented partitions ?

/boot and /root must be in primary others u can make it as extended partitions.

Take this with a grain of salt. This holds true only for old hardware. Old means something like 10 years old. Reason is that the bios can not access files on partitions after 1024 blocks (Not sure about the number but something like this).

Maybe just rephrase to "/boot and /root should be".

*smartass off*

Have /boot as the first primary, /tmp as the second primary, /root as third and the rest goes into the extended partitions. Which of whom you can have 64.

It's true that there are valid reasons for using different partitions,
but I've built LFS many times and always used just one.

That's just one option but it's a simple one and I've never regretted doing it that way.

Seven partitions seems a bit extreme, but you can have them if you want.

Edit to add : Swap has to be its own partition,
I forget it's there because all my linuxs share one.

Water under the bridge maybe, but when you say "/root", I think you mean "/"

I concur that you do not need all those partitions. Personally, I have:
/
swap
one or two for shared data--typically mounted at /home/data, and then linked as required

When I set up Windows on VirtualBox, I created a partition for the purpose and mounted it at ~/.virtualbox

Totaly right Pixellany. /root == /.
Also I meant swap as the second partition like moonfrog suggested.

As always fingers are way behind brain

Oke,

Now I wonder how big root (/) must be.
I have a 60G disk which i can entirly use for LFS.

If you go with the every-directory-one-partition idea root (/) just needs 15 (directories) * 4K of size. Just give it 100MB.
Else I'd go with 2G.
