Description Mark Purtill 2007-01-21 20:06:05 UTC 
If fcron-3.0.1-r2 is emerged with the debug USE flag, fcron will not run in the background.  This means the next time the system is rebooted, when the boot process gets to fcron, it will hang there, printing fcron debugging messages.

There's nothing suggestion such a radical change of behavior in the description of the debug use flag ("Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see http://www.gentoo.org/proj/en/qa/backtraces.xml."), so I think either the use flag here should be changed to something specific to fcron.  (ALternatively, the description of debug could be changed.)

Whether that's done or not, there ought to be elog messages warning about this behavior, since it will prevent the system from booting.

Don't use debug use flag globally, it's stupid.

Then please change the documentation on that flag in use.desc to reflect that.

Updated fcron-3.0.2 in CVS with a big fat warning.
