[SOLVED] Lost Power During pacman -Syu; Any Hope of Rescuing...?

Hi,
I was just doing pacman -Syu when all the power in my neighbourhood went out, resulting in these errors during  boot:

I've tried chrooting into the system from the Arch CD following many different online instructions, but it won't work (Input/output error). Is there anything else I can try to resuscitate this installation, or is the only solution to backup, wipe the HD and start from scratch?

Thanks!:)

Boot off the Arch CD, mount up your root partition (I'll assume you put it on /mnt) and run the following:

pacman -Syu -r /mnt

Let it run, and the reinstall the kernel for good measure.

pacman -S kernel26 -r /mnt

(Input/output error).

The filesystem seems to be broken if you're lucky. If you're not your hard disk is...

Try booting from a live medium and fsck on the partition.

Maybe also try reinstalling sysvinit: pacman -S sysvinit since

~ % LC_ALL=C pacman -Qo $(which init)
/sbin/init is owned by sysvinit 2.86-5

pacman -S kernel26 -r /mnt

That was quick!
Thanks a million to you, this (along with the forced reinstallation of glibc according to the same method) solved the problem.

Thanks again!
