 ...well, hmmph.

I ran a traditional/amd64 build with X and that took about 2 hours -but didn't record the time summary. also the make iso part was messed up because I forgot to put "sourcesets" before "iso-image-source".

Still! It takes half the time to compile NetBSD on a Linux VM than it does on a NetBSD VM. 

Hmmmph. 

This is on Debian 10.8, Virtualbox 6.1.18, 4 cores, for whatever that's worth
