Wouldn't work, MinePeon runs Arch Linux not debian .

But yeah, a pacman repo (that's what Arch uses) is in the works.  The problem at the moment is that MinePeon is in heavy development and so much changes between releases package management would slow things down to much.

However if you want to update Arch you can by doing;-

sudo pacman -Syu

Just don't blame me if it breaks something.
