It's that time again... First my grub broke. So I had to type my config manually: root (hd0,0) kernel /vmlinux26 root=/dev/mapper/lvmopraid-root initrd /kernel26.img boot

When you use xen-create-image to bootstrap an ubuntu, it sets up a grub config file menu.lst. However, this boot config is not kept up-to-date with newer ubuntu's because they use grub2 (which uses grub.cfg and not menu.lst). And Xen's pygrub first looks at menu.lst, so if you have a stale file, it will always boot an old kernel.

I don't believe in system passwords if they're not backup by some type of disk encryption. It's simply too easy to circumvent by changing a few boot parameters or by inserting a good boot disk. For performance reasons, I've decided against using full-disk encryption for my laptop and even against encryption for my home folder. This makes typing in a password to login a mere annoyance. Admittedly, my laptop features a fingerprint reader, but at the time I couldn't get it to work and it still requires me to type in my username, which I find just as superfluous. Also, fingerprints aren't that secure either.
