Portmgr committed the switch to the new default linux base port yesterday. After returning home from work I committed the corresponding UPDATING entry.
Today I marked all unmaintained/old linux base ports as deprecated (some are marked because they are EOL, some are marked because of bitrod). I use a expiration time of about 3 months. So while there’s plenty of time to update, you should do it now.
Just committed the FC4 port Boris did after Joe did the repocopy (Thanks Joe!). It seems this is the newest FC based linux_base port we can use with the current linuxolator.
