Recomended size for /, /boot, /tmp, /var, /usr, /opt partitions?

The disk to be partitioned are:
1 SSD drive of 240 gb shared with Windows 7 and a second SSD drive of 120 gb

You shouldn't need too much space for the root partition, I usually allocate about 20GB for my desktop Linux installs. I've been running an install of Ubuntu Gnome for about a year now and have used about 12GB of that so far which includes quite a bit of extra software.

You could probably get away with having about 10GB or so for the SteamOS root partition if you don't plan on installing too much along side it. The problem I've ran into with trying to have small root partitions of 10GB is that the system can run out of inodes which is kind of a pain to resolve.

Personally, I almost always go with 20GB just to be safe.

For post_install.sh to give a working clonezilla recovery image (made automatically at install time) you need a 10GB /boot/recovery partition.

I use

1. 10GB /
2. 10GB /boot/recovery
3. 10GB swap
4. as large as possible /home

The smallest drive i have used for SteamOS is 80GB.

You could use your ssd for all your SteamOS partitions and then use your second drive as SteamLibrary.

These are the values from the SteamOS installer.

You can get away with about 3GB for the first three, assuming you never receive any major updates

To be precise, the automatic drive setup is 10.2 ;) haha
Why* it is 10.2 and not 10, I do not know.

Partition 1:
Mount Point (use as): /
Size: 10.2 GB
File system: EXT4

Partition 2:
Mount Point (use as): /boot/recovery
Size: 10.2 GB
File system: EXT4

Partition 3:
Mount Point (use as): swap area
Size: 10.2 GB
File system: swap

Partition 4:
Mount Point (use as): /home
Size: maximum allowed
File system: EXT4

Why* it is 10.2 and not 10, I do not know.

The answer to that is the expression of the same figure in binary or decimal form. i.e. 10,200,547,328 bytes is expressed as 9.5GB in binary terms and can be expressed as 10.2 gigabyte in decimal. The difference is bits and bytes or b for bits and B for bytes.

Most drive manufacturers describe storage space using the larger sounding decimal version whereas most operating systems see and use the binary version which is why what the sticker says on your drive is nearly always larger than what operating system says.

So the correct point you tried to make is 9.5GB :-)

SteamOS post_install.sh only looks for partitions by mount point which means users can use any size they wish.

Oh, duh, how could I forget that lol.

[Balderick]

Another aspect that may contribute to the standard steamos install giving 10.2 partition size is sector size. 10,200,547,328 is divisible by 4096 for 4K sector size as well as being divisible by 512.

If in doubt, the source package is partman-auto. Read the algorithms in there.

Swap partition is not always needed, It will be used only if you run out of RAM, or want to Hibernate the computer. In this case, the Swap partition need to have a little more than you RAM size.

Swap partition is required for the recovery system - the Clonezilla config depends on it being there.
