Wine on 64-bit Ubuntu 12.04

[Lakorta]

Hi, I have a little problem with patching wine on Ubuntu 64-bit.
I read in the wine-wiki (http://wiki.winehq.org/WineOn64bit) that I have to

Add the following to /etc/schroot/schroot.conf, replacing your_username and the Ubuntu version accordingly:

Code: Select all

[precise]
description=Ubuntu Precise
directory=/var/chroot
users=your_username
groups=sbuild
root-groups=root 

Should I write it like this?:

Code: Select all

[precise]
description=Ubuntu 12.04
directory=/var/chroot
users=lakorta
groups=sbuild
root-groups=root 

And have I to uninstall my old wine before compile a new one from source?
