Indeed. However, in this case the problem is likely to solve itself, since
no-one will even know about the static apt/dpkg _unless_ they read the docs. 
And a DO_NOT_INSTALL_THESE.txt along with the .debs should do the rest. 
Debian sysadmins usually are not _that_ stupid ;-)

Are they really so ugly? (if uname -r != 2.2.* then "exit -1"? or something
with /proc/version?) And anyway, these are only non-mainstream temporary pkgs
(i.e. no need to get these hacks in the "regular" apt/dpkg source; the
"staticness" hacks aren't either). I don't see a big problem.

Yeah, I've thought of that, too. Only it doesn't work on anything < 2.1r4
(2.1r0's apt doesn't have apt-cdrom), so you'd have to fetch & (manually!)
install "half-new" slink versions first anyway. Also apt 0.3.19 fixes a random
(timing-related) deadlock thing in the CD handling, so if you're out of luck,
"apt-get install" from CDs "won't work as expected". (Never happened to me,
but I've seen several reports.)

Really, the static apt/dpkg method is the cleanest and most universal method I
can think of.
