You can do better than your old-school Unix experience with a pi and linux :-)
On the 1st gen RasPi the linux kernel took 10+ hours to build from scratch.
In contrast the plan9 kernel took one minute. The equivalent of FreeBSD's
"make world" for plan9 took 4 minutes. IIRC half of it was for ghostscript.
