Adding more persistent disk images

[proctor]

hi,

after looking in more detail at aufs it seems to me that using the tarred /KNOPPIX-DATA (really a tarred mounted /KNOPPIX/knoppix-data.img) with removed dot-wh-dot files should not disrupt an aufs file system because the tarred system is not overlaid into the UNION and so therefore not merged in the same fashion that aufs uses: they are simply copied into the UNION, into the aufs.

it seems to me that this is actually the preferred method, and not my patch (at http://www.knoppix.net/forum/threads...t-image-on-dvd).

would anyone disagree with this?

It will not disrupt the operation of aufs, but you will have inconsistant packages, your file system will have additional files and directories which should not exist, ie files and directories which should have been removed by package updates will re-appear in the "tar copied" file system. That's what I believe should be the behaviour of 'aufs'. Your views may differ.
