Since Current is a development branch you'll need to make sure you are reading the current mailing lists. Also ensure you read the UPDATING file in the /usr/src folder.
One thing to remember when installing current on a machine where you want it to be relatively performant, is that by default it has debugging symbols enabled. So you will have to disable this if performance is an issue. To do this you need to update the /etc/src.conf and the /etc/make.conf with the following:
/etc/src.conf
WITH_MALLOC_PRODUCTION="YES"
WITHOUT_LLVM_ASSERTIONS="YES"
The above will remove any of the debugging and assertions in the build world process.
/etc/make.conf
KERNCONF=GENERIC-NODEBUG
The above will using the non debug kernel config when you compile the kernel.
Note the make.conf contents and the WITHOUT_LLVM_ASSERTIONS came from a klara systems article. The WITH_MALLOC_PRODUCTION is in the UPDATING file in /usr/src.
Make sure you are using the latest main branch in /usr/src. If like my install you will need to pull down fresh repo from github. The way I did it was the delete everything from /usr/src. Be careful as to not whipe out anything else. Then running something like the following:
git clone https://git.freebsd.org/src.git -C /usr/src
Then do a git branch to see which branch you are on. You should see something like:
* main
stable14
Where main is the current branch. To build the current branch the instructions are in the handbook. To summarise you should do something like the following:
# cd /usr/src
# make -j4 buildworld
# make -j4 kernel
# shutdown -r now
# etcupdate -p
# cd /usr/src
# make installworld
# etcupdate -B
# shutdown -r now
You should now be using current. Now one of the next things you should do, expecially if you've come from a Release version is upgrade all the packages. Something like the following:
# pkg update
# pkg upgrade -f
If it updates any kernel modules that handle graphics you should reboot.
