Reinstalling Linux: a checklist

I thought it would be nice for people to have a checklist of what they need to back up before installing a different Linux flavour.

• /etc - system configuration
• /home - your files and configurations
• /boot/grub/menu.lst or grub.conf
• /var/httpd - only if you're running web services and using the global directory; on some distributions, this is not placed in /var (e.g. in Arch it's in /home/httpd)
• do a mysqldump if you're using mysql; similarly for any other relational database
• dump your package list - sometimes this is done by reading file names from /var/cache/pkg or similar after cleaning out old package files; some package managers will output a list (something like dpkg --get-selections on Debian and derivatives)
