so far using chroot and env GB_DIR all fails to work for manjaro.

your second suggestion there i think was my thinking, the version info is
in that file somewhere, i gotta be able to find it somehow.
I'll look into it.

If the only option is the "load a VM" way then i think i'll just stick with
my "luck" method as 9 out of 10 is pretty darn lucky ;)

Thanks bruce, Ben

Well wishes
