11 I used to take a different approach. Instead of a VM I used a chroot
12 that was a clone of the netbook, except that make.conf in the chroot
13 included buildpkg in FEATURES and the netbook's make.conf have --usepkg in
14 DEFAULT_OPTs. PKGDIR was an NFS share accessible to both.
16 Then I would simply emerge whatever I wanted in the chroot, then emerge it
17 on the netbook. No messing around with distcc, which will always run some
18 stuff on the local system, instead everything but unpacking the package
19 tarballs was done in the VM.
21 This approach meant that I could easily script the build process for
22 several systems, including a 486 box was running at the time. I later
23 switched to using systemd containers instead of chroots.
