I agree, but tags are usefull.


Here you are an example with linux-libre:


$ git clone https://gitlab.com/aitor_cz/linux-libre.git
Cloning into 'linux-libre'...

$ cd linux-libre


$ git checkout gbp-master/3.16.7-gnu-6
Note: checking out 'gbp-master/3.16.7-gnu-6'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b new_branch_name

HEAD is now at c17308d... modified: debian/changelog


$ ls
arch     CREDITS  Documentation  fs       ipc      kernel Makefile  
README          scripts   tools
block    crypto   drivers        include  Kbuild   lib mm        
REPORTING-BUGS  security  usr
COPYING  debian   firmware       init     Kconfig  MAINTAINERS net       
samples         sound     virt



$ git status
HEAD detached at gbp-master/3.16.7-gnu-6
nothing to commit, working directory clean


We have a *detached* HEAD, and we can't work in this stage. Let's give a
name to the branch:


$ git checkout -b the_name_of_the_branch


$ git status
On branch the_name_of_the_branch
nothing to commit, working directory clean


HTH,

Aitor.
