I boot a 64 Xenial XFCE full puplet .iso that I've recently discovered in .pet form (i.e., installs the DE to Mainline JWM from .pet).
The puplet is usable overall but the .pet is less bloated. E.g., LibreOffice is not included by .pet, while it's not removable by automation in the full puplet.
When I boot the XFCE .pet, it tries to load JWM first, struggling before eventually rendering XFCE.
This .pet wouldn't support a pupsave. I had to covert it to ydrv for use (makes sense as peebea does not release alt-DE .pets but ydrv).
I looked at rc.local which is referenced from rc.sysinit, but jwm is not mentioned in the scripts.
How to skip JWM on the way to an alt-DE?
