16 The latter, it happens from time to time. I see it here about once every
17 2 months or so (i.e. seldom). I suppose this is the best we can expect,
18 seeing as how it all works:

20 @preserved-rebuild tries to remember everything that uses everything and
21 detect changes, this will never be 100%,
22 revdep-rebuild actively looks for brokenness and still sometimes gets it
23 wrong (dynamic plugin modules anyone?)

25 The specifics depend on the exact package. Maybe also file a bug so Zac
26 can look it over just in case there in a useful tweak he can make
