FreeBSD Upgrade System

1. Update your source, we mentioned earlier that update source does not represent an upgrade
, a compiled action is still required.

Compiling source
1./usr/src#make World
This command can be divided into two steps make Buildworld and make Installworld
Make Buildworld--> can be done in multiple-person mode
Make Installworld--> will cover the system, preferably in single mode,
In the multiplayer mode, there is no way, the wrong one to do it again.
Factors in multiplayer mode: server cannot be shut down for too long.

a./usr/src# make-j4 Buildworld-> with 4 make

* After make the/usr/obj can be shared by NFS

b./usr/src# make Installworld

Re-edit kernel after upgrade
* GENERIC may not change but source may change ~ ~
* Buildworld Error There may be a problem with coretram, if so, try again in a few days

/usr/src# Make clean Cleandir
Clears the directories and files generated during the compilation process

Replacement of/etc under the set
# MERGEMASTER-CV

Previous 2 selections can be skipped with enter

--> says the current system
-----> presentation of new Systems
！ --> means different places.

* Usually have a moving file to pay attention, or by the space skip
After that, each file will have 3 option 1. D to remove the new
2. I install a new
3. Together

* After a series of choices, the last one will come.

Select Yes to retain those files that have not been moved to delete!
