IMHO, this is worth It's mentioned in /usr/ports/UPDATING (as in: make sure you don't =20 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 =20 may change the behavior of linux programs (in -stable you may see =20 coredumps when you change the sysctl) and that bug reports with a non =20 default value will not be taken care of. The intend is to change the default value to 2.6.x when the code is =20 stable enough. So we don't need to name specific values for osrelease, =20 I think.
