[Samba] Updating Samba

[Zane Zakraisek]

I'm pretty new to compiling software, although I would rather compile my
own Samba 4.0.0 server rather than wait for it to become available in the
repositories of my distribution. How do you update compiled software. Like
if I compile and install Samba 4.0.0, and then 4.0.1 comes out, Is there a
way to update to that without starting from scratch and having to rebuild
my domain? Thanks can I simply update my Git tree and then compile again,
or will that delete everything
