Advise needed on partition layout for building Linux from Scratch

johncsl82 · 05-21-2010, 12:08 AM

Hello People,

This my first attempt to make a Linux from Scratch.

Using cfdisk I will create the following partitions:

Code:

/boot (primary) (FAT32) 100 MB

/     (Logical) (ext3)  5900 MB
/usr  (Logical) (ext3)  8000 MB  
/home (Logical) (ext3)  3000 MB
/opt  (Logical) (ext3)  5000 MB
/tmp  (Logical) (ext3)  2000 MB
/var  (Logical) (ext3)  2000 MB

/swap (Logical) (swap)  2000 MB

Total amount of hard disk space required is 30000 MB (30 G)

I need some advise and feedback regrading the partition layout.. like which partition that I need to increase to decrease its size....

Thank you.

Hi,

1) Why is /boot a FAT32 FS?? Why not ext3 like the rest.
2) swap size depends on your total memory (a rule of thumb: 1.5 times physical memory, although nowadays swap isn't that "strict" anymore).

The rest looks ok, although /home seems a bit small.

Is there a specific reason why you want to split things up this way?

/opt might be too big, but that depends on your decision once you start installing Xorg (see BLFS Introduction to Xorg-7.2). You can decide to use /opt, but can also use /usr.

Hope this clears things up a bit.

I will increase the /home to 5000 MB (5 G) and decrease /opt to 3000 MB (3 G).

I just want to learn how to layout the partition in a correct manner so that it can be fully utilize.

Thank you.
