Re: [opensuse] small installation help
On 2011/10/30 19:35 (GMT+0530) Linux Tyro composed:

by default openSUSE does this:

one SWAP partition
one root partition "/"
one home partition "/home/"

The two partitions '/' and '/home' are separate? But as you have
mentioned that, /home, 'home' itself is coming inside '/', and still
is different partition? What I know by partition, means that it is
getting some 'sda1/2/3/4/*' no., is it like that?

SWAP partition is disk space that is reserved for paging, this is a bit like
allocating part of your hard disc to act as additional RAM.

So when PC is off, SWAP is empty?

Sort of, unless "off" means suspended. If suspended, it gets reloaded into RAM at startup. If not, whatever was there at last shutdown is treated as free and available even though technically not empty.

Also should I make separate root ("/") and home ("/home/") or not,
would it be beneficial in any way(s)?

Usually it makes good sense to create separate / and /home partitions. It facilitates OS upgrading by not requiring that you backup your data first and also need to restore it afterward.

Should I allocate the separate memories to each of /tmp, /var, /home,
/, and what is the purpose of doing it separately rather than what the
installer does it by default. Would it be beneficial? However, I am
currently just replacing my Ubuntu LTS with openSUSE and remaining
windows xp intact.

Such an inexperienced user as you would do well to avoid micromanaging partitions. The most such a person should consider would be separate /, /home, swap & /boot, and probably not /boot either.

Except -> if you wish to plan ahead for upgrading or experimentation. It makes sense to reserve an extra same size partition for / (or two or three) to be used for upgrading to a newer release or for experimenting with a different distro entirely, or for testing a development release. Having extra partition for / for this purpose enables upgrading or testing without materially disturbing your existing installation. I use the word "materially" because certain user settings can be changed by a newer or alien release, and such changes can disrupt reversion to your original OS version. Such disruptions can be avoided by using a different user login (not sharing data directly) until permanent upgrade or switch is desired, or doing all testing using only a root login.

Before deciding on partitioning, with or without use of LVM, and before beginning installation of whatever you download, I suggest some further reading:
