Computer got hosed

So arch wasn't downloading anything from AUR, I went through all kinds of steps to try and fix it, nothing worked. I left on a trip for a few days and when I cam back AUR was working again, I though all was good until I started some updates, first none were found so I just tried installing some stuff, thats when I figured out my installed package database was gone. After the fact I learned how to backup a list of installed packages and even how to restore your installed packages based on a log file. This is where I will say don't cut corners, follow the wiki and don't think you have a faster way. Instead of recreating my installed file list I just reinstalled all files. Well a reboot later and computer wouldn't boot. My mkinitcpio.conf was overwritten with the base defaults. At boot there was no LVM loaded and thus no boot :-(. Well two hours later everything was up and running, very glad I use seperate LVM drives for configuration files, backups and the such. There are quite a few parts that I cannot easily backup that way, so now I get to go through getting all my hardware to work again. First up is my Razer Anasi.I use some of the macro keys to send ir events through lirc to control my tv, I didn't realize how much I used this so now on to getting that working again.
