> However, your scripty seems fine, too. Could we add a switch to conform with gnu's cp -au? Just not to overwrite newer files. I don't know there is an option there in 'tar' (I can't see in  in tar(1)). At least we have the 'k' modifier, which could help.

Tar's -k modifier is the nearest I can find. Mkext has no such option and I've found no cpio (thankfully?). I don't know where to look for or suggest such an option. It may seem natural in tar, but there's a danger with archive utilities that their feature list may grow well beyond a comfortable size for the ordinary user.

Also a copy which omits files would be much faster if it did not read the files which it is going to omit, which rather rules out archive_util | archive_util usage. I think the option would be better added to arisawa's cpdir, but I'm too lazy. :)
