20140922: AFFECTS: users of emulators/linux_base-f10 and emulators/linux_base-c6 AUTHOR: xmj@FreeBSD.org The complete drop-in replacement linux-c6 port infrastructure is in ports and will shortly replace the current linux-f10- ports as default. To switch to the linux-c6 infrastructure you should: 0. Backup all your vital information! 1. Remove the current linux base port and all linux-f10- ports. 2. Add the following lines to /etc/make.conf: OVERRIDE_LINUX_BASE_PORT=c6 OVERRIDE_LINUX_NONBASE_PORTS=c6 3. Make sure no linux application is running. 4. Set appropriate sysctl (compat.linux.osrelease=2.6.18). 5. Install emulators/linux-c6. That should be enough in most circumstances. If you experience difficulties, please be sure to expand step 1 to: 1a. Remove all ports which depend on linux base port. 1b. Remove linux base port. 1c. Clean /compat/linux/ directory. Should you encounter any other difficulties not fixed by these extended steps, please submit an issue report in Bugzilla and send an email to FreeBSD's emulation@ mailing list.
