Comment 1 for bug 23938

/etc/logrotate.d/apache2 is a conffile, meaning your changes won't get
overwritten by us on upgrade, so feel free to change your local version. The
default is to do a hard restart because we've seen many other instances where
graceful would cause the server to die completely when some rogue extension or
other segfaults as the parent reloads, leaving you with NO apache from 6:25
onward. I decided at that time that the current compromise was the lesser of
two evils.

I'm still trying to figure out the best way to serve everyone well here without
the world blowing up. ;)
