This will try to automatically determine if the current tree is a
|
||||
release tree by looking for git tags that belong to the current
|
||||
top of tree revision.
|
||||
|
||||
A string of the format -gxxxxxxxx will be added to the localversion
|
||||
if a git-based tree is found. The string generated by this will be
|
||||
appended after any matching localversion* files, and after the value
|
||||
set in CONFIG_LOCALVERSION.

$ git rev-parse --verify HEAD
