The "emerge depclean" countdown and warning are useful in some cases, but also annoying in other cases (frequent usage, automatically maintained systems). Regarding the countdown, I suggest using a "DEPCLEAN_DELAY" variable in make.conf similar to "CLEAN_DELAY" for "emerge clean", shutting it off entirely (so it does not produce any output) with "DEPCLEAN_DELAY=0". The warning (and IMO even the statistics) should be suppressed by the "--quiet" option to emerge.
Created attachment 65213 [details, diff] emerge.patch The patch removes depclean warning when --quiet is used. Countdown can be removed by setting EMERGE_WARNING_DELAY to 0.
Fixed in 2.0.53
Forgot to mark it.
