Re: master^ is not a local branch -- huh?!?

First, I'm afraid that "Checking out commit 'foobar'" might be confusing
as this may happen through either a remote branch, a tag, or any random
commit.  It seems to me that "Checking out 'v2.5'" is less confusing

than "Checking out commit 'v2.5'".  But that's a minor detail and
probably a personal preference.

To the contrary: this "detached HEAD" is exactly what you need if you
want to relate to any documentation or perform a search for more

information.  Like it or not, this detached HEAD term is exactly what
this Git concept is all about and how it is designated everywhere.  The
sooner Git users see and learn about it the better.

As I am not good at keeping track of different proposals to change this
word here and that word there, I expect this will probably need at least
few rotations of earth to get input from people in different timezones,

and I think this is post 1.7.0 item anyway, I'll queue the attached draft
in 'pu' and keep it there, to make it easier for others to tweak the
message.

Would it be a safe assumption to describe a 'detached HEAD' state as
being synonymous with a (local) personal scratchpad or temporary
workspace based on and from the original committed object?

If this assumption is correct, then maybe this notion of a scratchpad
may be more intuitive and conceptual to new users without getting
bogged down with the necessary semantics of the terms used, but can
also preserve references to 'detached HEAD' in the documentation for a
fuller explanation.


A scratchpad or temporary workspace description alludes to its semi
permanent nature, and can warn that the subsequent commits may be lost
through aging and garbage collection until the user "commits" to
saving their progress through the creation a new branch, and thereby
making them permanent.


I must say the explanations presented in this thread have shed some
light on what is on the face of it a common trap that leaves new users
wondering "What happened to my work!" and I thank you all.
