elog PKGBUILD for review (AUR)

I would appreciate feedback on this PKGBUILD before I submit it to the AUR. It includes boot and install scripts, new user and group ID's, and other things I have not done before. I used other Arch examples as models, but I might not have fully understood what I was trying to emulate.

elog uses the filesystem as a database to log/timestamp and serve back information submitted via http. I think it is a great program, carefully designed, stable, and actively supported. I would recommend it to anyone who needs to log/timestamp information and either: a) wants the information to remain accessible to scripts and not disappear into a large binary blob, or b) doesn't want to install and maintain a normal database.
