I'm about to install Linux on an iMac (DVSE 500mhz). I haven't used Linux on a Mac since PPC on an old PM4400 long time ago, and it's the first time ever I'm setting up a Workstation. I have some experience with Linux Workstations on i386 though.
YDL have just released 2.3 with these improvements (among others):
"kernel 2.4.19, CUPS, apt-get, OpenOffice 1.0, Galeon 1.2, Evolution 1.0.5, AbiWord 1.0.2."
Looks like they are actually switching to apt-get! Seems very promising, I think.
But there's also Mandrake 8.2.
Does anyone have something good to say about Mandrake/workstation (I already have the install CD's), or is YDL the obvious choice.
