4.2 and Patches question

Hi guys,

I tried to add the all in one patch for hobbit 4.2.0 and it run smoothly when I issued the command [root at hobbit hobbit-4.2.0]# patch -p0 <allinone.patch

So my next step would to re-configure, re-make and re-makeinstall, is this right?

Is my old configuration would be safe without backup if I'll do the next step?

Thanks in advance!

Regards, Ryan
