GIT cherrypicking - commit something fast to live

Lets say you need to put something to LIVE site fast. And you go and check what is currently in line to get pulled once you fire git pull (   and see there are other branches/commits coming and you are dont know is it LIVE material. There is a side route for this cases. You can cherrypick specific commits by their HASH id.

So you go to live git directory, make git fetch and then write 

git cherry-pick  68213c9548a03c176484d18c8986c77dcadfe76c

where this ID is SHA-1 value for that commit. With this command you have just put this commit to LIVE site and made a hotfix that way. This only works for commits, merge commits wont work.
