How to group root subfolders among partitions?

StrangeAttractor · 2010-07-16 23:11:55

After a cup of coffe, planning a new system, I've came to conclusion that it'd be logical to split the filesystem hierarchy into 3 partitions (to reserve free space for groups of them rather than for each one):

1. bin, sbin, lib, etc, root.
2. usr, opt
3. var, tmp, home

How do I best achieve this? The only idea came into my mind is putting opt inside usr and creating /opt as a symlink to /usr/opt, with home and tmp placed same way inside var. Is it a good idea or not?

BTW I use LVM2 for everything except /boot and I only use /home as a place for user-specific programs' settings files, all the data of mine (projects, downloads, etc) is stored on a separate partition.

So / would be a union mount of the three partitions?

Yes, if it is called so. Now, it is of 2 (/home and everything else).

plan 9 union mounts!

aufs might be able to pull this off... it certainly won't be pretty... Keep in mind that you need a bunch of directories to be available immediately on mounting /, so they all need to be on the same partition. I don't know all of them offhand (sbin, bin, lib, etc, root, ...), but it's likely somewhere in the Beginner's Guide or the Official Install Guide on the wiki.

Why would I need all that? Why not keep it simple and just use the solution I've offered (some symlinks)?

Symlinks should work just fine, at least for /home I have used this approach in the past. I don't see a reason why it shouldn't work for the other directories.
