Next version (7.0) will be based on Arch with pacman as the default package manager, I will remove firefox and gparted, and add pacmanXG GUI for pacman. Other applications like mplayer2, deadbeef, evince, gpicview and Puppy specific like sfs-load and pwireless will stay; system should be usable out of the box. Also I will keep specific things like tint2 with mouse over patch, simple-radio with nice notifications, desktop settings, mounting and wallpaper changer scripts...
I had to recompile mesa package https://www.archlinux.org/packages/extra/i686/mesa/; converted from Arch it was 40 MB , now is 2.1 MB , but iso size for now is 162 MB with fast gzip compression.
