Can I mount one partition to two folders?

Would I be able to mount the same drive (partition) to 2 folders?
like for example:
mount hdx(#) to /home and /usr at the same time so that they both use the same partition

you want the contents of /home to be the same as the contents of /usr ???? how does that make any sense?? if you mean you want to store the data seperately in different locations in that partition, you could just use a symlink from, say, /home to /usr/home or something... not nice at all though.

Yes you can, but I don't see why you would ever need to.

And I also have another question:

Also is it a good idea to put /root onto it's own partition (or not)?

A simlink is kind of like a shortcut. You can make them using "ln -s." Check the man page and info page for more details.

There's really no need to put /root on its own partition, its not used much normally anyways.

I am just wanting to keep the /root config files (/root/.(whateverprogamthisis)) out of the "/" partition (which will be about a 1G partition)
And also thanks for your help.

Are you only making the partition that you will mount "/" 1G? This will not be enough room unless you are running a very low lever system, like a router. Most everything goes in "/", so you will need to make this partition much bigger. I don't know you situation though, so if you know what your doing, you can just ignore my comments.

That's actually quite a bit of room for / based on what I've run into. I'm currently only using 140Mb of the 1Gb I allocated to my / partition (Note: I have all my other major filesystems broken out of / and mounted seperately). If you are not breaking out your filesystems into seperate mountpoints then I agree, 1Gb would only handle a very lightweight install.

Code:

$ df

I would never advocate anything this complex--mostly because I project myself into the picture and know that **I** woudl not be able to keep track of what is going on.

Do you get a performance benefit in your scheme?

There is the bind option while mounting another directory to a certain directory that is already mounted. For an example, you could use bind for /tmp and /var/tmp on /dev/shm to increase performance. Another example is when you want a directory to share the same directory with out using symbolic links on a SAMBA server. There are other mount options.

The correct term is directory not folders. This goes the same for Windows too.

This seems needlessly complex.

The more complex it is, the easier it'll break, and the nastier it is to fix when it does.

Keep it simple.

I highly doubt it. I set things up in a complex way because I like to learn through experience. Is it necessary to have all seperate mountpoints and three LVM volume groups like on my home system (below)? Of course not. It's ludicrous. But I learn by doing, and so I did this to learn. I also take LVM snapshots to do my backups. Again, not necessary for a home system, but a good way to learn. If that makes any sense?!

Ahh, shucks ... that is my simple system! :rolleyes: My more complex one is at home:
