Install on a PowerPC G5

Quote from Zippitysplat

Is it possible to install OMV on a PowerPC G5 Power Mac and if so what would the process look like.

In general omv is arch agnostic. ISO's are provided for x86 only and some raw images for arm.
A normal procedure out of those archs would be in this case would be to install first a supported debian version (wheezy or jessie) for ppc, then install omv on top as the tutorial in the guide section indicates.

omv-extras.org doesn't have a powerpc repo for most plugins but you might be able to install them manually.
