16 The profiles differ, and as Jeremy explained, most of @system packages

30 It does this ugly/nasty hack, because environment stuff needs to exist,
31 uptil the point that you have a sane toolchain. That's about when you
32 are instructed to run `emerge --sync`, which wipes out these
33 modifications *on purpose*. The `emerge --sync` hence serves two
34 reasons, skipping it, or doing it sooner guarantees some problems to
