How about something like this? It ignores attributes that should have no bearing on whether the kernel is considered dirty. Copied trees with no other changes would no longer be marked with -dirty. Plus it works on read-only media since no index updating is required. Would this also be considered kosher, at least for the purposes of setlocalversion? diff --git a/scripts/setlocalversion b/scripts/setlocalversion index 71f39410691b..9da4c5e83285 100755 --- a/scripts/setlocalversion +++ b/scripts/setlocalversion @@ -73,8 +73,10 @@ scm_version() printf -- '-svn%s' "`git svn find-rev $head`" fi - # Check for uncommitted changes - if git diff-index --name-only HEAD | grep -qv "^scripts/package"; then + # Check for uncommitted changes.
