Noooo use tagline - as it defaults to explicit when there aren't

Edit the {arch}/=tagging-method file. There are regexs there that help
arch define what is treasured source code, what is junk (and ignored),
what is unkown etc. Very easy to make it do what you want it to.

Even better - if we start adding taglines (unique, unchanging tags) such

 * arch-tag: DO_NOT_CHANGE_b85434bac70c3f186e66c110805ec317

then we can move those files with impunity. Arch will keep the history,
and be able to continue to patch it from other archives.

Ideally we would go and create a new base kernel archive.... with a tagline
in every file as it appears in 'history'.

I'm half tempted to try and do this actually...

If I understand you... then you're correct. Your looking through CVS
glasses. In the arch world branches are cheap and easy, so use them.

Branch... :O)

The Category and Branch are just for you to organise your archives
nicely. Even the Version isn't really used much - except to get the
latest version of Cat--Branch if you don't specifiy a version.

Really looking forward to the day Linus and co' are converted to the
Open Source way :O)
