Re: tracking perms/ownership

Do you think its OK to cache this stuff in the index, though?
write-tree could then just dump the perms/ownership out as gitattributes

I'd really prefer not.

The index state - very much by design - matches the filesystem "stat" 
data, not the internal git data. So "ce_size" matches the checked-out 
size, not the native git data size (ie with CRLF conversion, it matches 
not the checked-in data, but the filesystem version). 

And the same really goes for ce_uid/ce_gid: they have to match what's on 
the filesystem, because they are used not to track user information, but 
to verify that the inode data is valid!

Yeah, we could just ignore them for checking "is the inode the same", but 
that would actually end up *defeating* the point of what you want to do: 
at that point, we'd also obviously ignore it when ownership changes!
