However, I also think that Andrew has a good point in that the behavior across Linux filesystems (ReiserFS, ext2, ext3, minix, etc.) should be consistent. Either they should all update ctime during renames, or none of them should. Anyway, I'll try to work with the GNU tar maintainer to get this problem in tar fixed. It'll probably be a lot harder to fix in tar than to have ReiserFS update ctimes since it'll require major changes in the --listed-incremental snapshot files. However, if you don't think it's a good idea to make these changes to ReiserFS then we'll just work on fixing up tar.

(I think I am.) Would you be willing to submit a patch for tar instead?
