Reinstalling arch without touching /home

Hi!

I really messed up my filesystem in library. I added to pacman multilib; I did pacman -Su and something goes wrong.. never mind..

1. I tried to set up new arch without touching everything, I was thinking that when I install base category I repair base components (include library  /lib and /usr/lib ) but it was the same, so.. Is there any solution to do this?

2. If not...
I have / mountpoint and /home on the same partition. My whole data are on /home it's over 400gb.
How can I seperate /home directory to new partition WITHOUT touching the data, and then reinstall my arch OS?

Re: Reinstalling arch without touching /home

1. Have you tried

pacman -Syy base base-devel

(you may need to force the install of some packages)

2. i) if possible back up your data or at least the most important stuff

ii) http://embraceubuntu.com/2006/01/29/mov … partition/, It says ubuntu but you can use arch still, you will need to make sure the new partition is big enough though and I'd still recommend having a backup of everything you can

Re: Reinstalling arch without touching /home

As a simple and quick solution, make a new partition for your root, say sdaX. Then, delete everything except home on your current partition, say sdaY and move everything from sdaY/home to sdaY/. Your data will stay here so this won't take much time to move.
Then install fresh arch to sdaX.

I think you mean you do not have a seperate mount point for /home, so /home resides on root? In this case, you can also just delete everything besides /home from the arch installer environment, then start the setup and install arch. Now I do not believe the installer will recreate-override /home, but anyway you can rename it to something else for the moment. Just make sure not to select "create new filesystem"...

... and backup...

Just to add to this, you will need a Live CD/USB to do this.  I'd suggest Ubuntu, because gparted is already included.

But you probably already knew that
