When I just started to read planet.debian.org today, I realized that Russel Coker was speaking of an unknown tool to print the UUID, but that Debian version doesn’t seem to do that.
It’s called fle apparently.
Sadly, an apt-cache showed that there’s no package named fle. Then I realized that he was actually speaking of the good old tool called file – with an I between F and L!
Really, I wish the font rendering will improve in Lenny as this was on Etch… *sigh*
