Tip: Find yourself a restore disc/usb WITH xz compression support

Something went wrong with an Syu on my netbook and the system was non-functional. glibc was broken, though I'm not entirely sure how. screen or pacman crashed while glibc was being installed.

No problem, I'll boot from my arch live USB and extract the glibc package. It's a fairly old installer, but it works for the rare recovery situations. However it didn't have xz support - and I couldnt extract glibc. Fortunately the current xz-utils package is not xz'ed itself and I was able to wget that off ftp.

Anyway, just something to keep in mind

hope it helps someone,

James

New install media is coming out soon!

If anyone is looking for an extensive liveCD, I recommend SysRescCD. It's helped me out of horrible things (and helped me DO horrible things) on several occasions.

You don't have to wait for new install media -- the 2009.08 install ISOs contain xz, and more recent ISOs are already available from http://build.archlinux.org/isos/.

Heh, similar thing happened to me when I switched to ext4 before install media had a kernel that supported it.  I broke grub and couldn't mount the drive as writable without ext4 support.  Ended up having to make a persistent usb drive, install, upgrade, and then use it to recover...

I've learned to always have install media that supports new low level technologies now

Did you test grml.org it has everything one ever needs for rescue pruposes. It also ahs quite updated software so I'm pretty sure it has xz
