A post on a LUG list praises it under that name, which .deb distros apparently still use; Wikipedia made it clear that .rpm distros no longer do, alas!, but got me totally confused about what I should tell yum to install so that I can try it. (I had hoped "yum install palimpsest" might link to current jargon, but it didn't.)
I'm using XFCE on F18, and I think Applications Menu -> Accessories -> Disks is what you want. Not sure what it is called, it doesn't seem to have an ABOUT menu....
