IMHO, this is worth It's mentioned in /usr/ports/UPDATING (as in: make sure you don't change the default osrelease). > mentioning in the linuxolator documentation because it's not > immediately obvious and it's likely to bite someone in a non- > obvious way. It should be mentioned in the official docs that a non default value may change the behavior of linux programs (in -stable you may see coredumps when you change the sysctl) and that bug reports with a non default value will not be taken care of. The intend is to change the default value to 2.6.x when the code is stable enough. So we don't need to name specific values for osrelease, I think.
