[Samba] upgrade procedure

[Cristian Saavedra]

Hello

I'm upgrading to 4.0.4 as far as i remember the samba_upgradeprovision must not be used, so i'm asking for the current upgrade procedure:

- configure samba 4.0.4
- make
- create current samba backup (just in case)
- killall samba process
- make install
- run samba

After that, the new binaries are in place, should i do something else? run an script? delete a file? anything?

Thanks.
