In particular, the script currently in U-Boot does not describe commit f8bbb4dad0e9d91b7a51d6cc54dcf66d142f50fe correctly, resulting in a version of "2011.09" instead of "2011.09-01460-gf8bbb4d". With that commit checked out, the command "git name-rev --tags HEAD" gives this result: HEAD tags/v2011.12-rc1~30^2 Then the "changes" regex does not match because of the trailing '^2': grep -E '^HEAD[[:space:]]+(.*~[0-9]*|undefined)$' The new version of tools/setlocalversion in the kernel correctly handles those situations by using different plumbing commands. The version from the kernel is not directly usable as it has code for supporting CONFIG_LOCALVERSION from Kconfig, but the version that was imported is very similar to the one in Linux v3.2-rc4.
