Correct.

The chosen disttag whichever it will be, needs to be backwards
compatible to the previous releases to allow for proper upgrade paths,
e.g. it need to be rpm-newer.

For example if you change the disttag from fc6 to abc1 then
foo-1.2.3-4.abc1 will appear older to rpm than foo-1.2.3-4.fc6, so no
fc6 package would ever upgrade to an abc1 package.

Therefore we shouldn't use abc1 as a disttag :)

Jokes aside - what happens with abc1 happens with "f7", too. f7
packages would again appear older than fc6 and even fc5 etc. packages,
so all upgrade paths would be broken. That's why one needs to think
about the disttag, and it looks like people prefer to stay in line and
use fc7.
