[Rock-dev] 'autoproj update' always checks out master branch of autoproj subdir

[Sylvain Joyeux]

I did find one bug during bootstrapping, where the branch (and for that 
matter, any VCS options given on the command line) would not be saved 
properly. This would lead the first "autoproj update" to checkout master.

Moreover, "autoproj switch-config" is also buggy, as it does not update 
the branch as it should.

Now, after rereading your mail, I'm not entirely sure what you are 
experiencing.

The autoproj/manifest file does *not* contain the branch of the master 
configuration. It only contains definitions for the "package sets" (i.e. 
stuff that lies in autoproj/remotes/)

The VCS definition for the master configuration is stored in 
autoproj/config.yml. You can edit/change this file yourself, but the 
preferred way is to do

   autoproj switch-config VCSTYPE VCSURL VCSOPTIONS

As a shortcut, if you only want to change VCS options (as e.g. the 
branch), the vcs type and URL can be omitted.

   autoproj switch-config branch=toolchain-2.3

It is preferred, as autoproj should restore the old configuration if 
checking out the new one fails.
