[SOLVED] Problem with mountpoints, partitions ... WTHIWIG

WTHIWIG - What the hell is what I get // or what I've done ;]

On my fresh 1 day old installation I've got such strange behavior:

Could not chdir to home directory /home/user: No such file or directory

I'm suspecting the cause of that could be update of "filesystem" where "mtab" where with conflict during updating.
As far as I remember I cleaned up it or even removed (probably the stupidest thing I've made for some time ;]). Several restarts later I noticed problems with /home/userDIR.
In the way of trying to repair that I've copied (especially /proc, /sys etc. mount points) and changed "mtab" from my second Arch installation but nothing helps.
I can manually mount /home, /boot and then they appears

It seems a little suspicious that /, /tmp, /boot and /home are all *exactly* the same size and have *exactly* the same ratio of used to available bytes? Or do you expect that?

Do you have dump installed?

As far as I know /proc /sys etc. are recreated on reboot so you shouldn't need to copy them. mtab should be a symlink. Is it? If so, where does it point?

When you say you can manually mount them, how exactly? Does e.g. just mount /home work? Or do you have to use another command?

That's right, something is wrong with size of mountpoints, because / /home /boot have different size.
mtab is not a symlink (because I deleted it so it was recreated as a file not a symlink.
As I saw on working machine it should be:
/etc/mtab -> /proc/self/mounts
After deleting mtab and symlinking it properly everything woks fine ;]

Thanks for help
