Well, we already do that, in fact :

    (split (/ /, $ramdisk));

But the problem is not how to split it, but how to detect it is of length 1,
that is having the legacy single entry in the field.

Not sure if allowing copa, colon or whitespace delimitation clashes with the
filenames though, as some may use comas.

No way, i think you are misunderstanding here. The current code does :

Using $ramdisk to build the ramdisk.
Other suitable ramdisk generating tools : @ramdisklist.
Full list of probed ramdisk generating tools : $ramdiskorig.

And we will replace it with (shell version given) :

db_subst kernel-package/postinst_ramdisk $ramdisk
db_subst kernel-package/postinst_ramdisklist $ramdisklist
db_subst kernel-package/postinst_ramdiskorig $ramdiskorig
db_input high kernel-package/postinst_ramdisk_verbose_output || true

And then list in a template file those kernel-package/postinst_* with the
corresponding text above, and so on. 

This allow to translate those templates, to select different questions at
different priorities, and do generic preseeding of those responses for
automatic installation. Not to mention its effect on usability and such.

Furthermore it has been since before sarge policy that all user questions need
to use debconf, and it was only skipped because Manoj didn't want to do those
change (probably for lack of time), and nobody jumped in. Now is the time

Does that clarify it, and if not, please explain how i could put this in a
helper tool ?
