[PATCH 15/16] init: expand comments explaining config trickery

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

then re-read it. There are some comments explaining what's
going on here, but they are not grouped very well with the
matching code. Let's rearrange and expand them.
