Yes, that is why I say "Probably the facilities already exist".
[But in fact I wrote a lot of partition management code
and put only a bare minimum into the kernel. This just
suffices to do a few things. Adam Richter recently expressed
his satisfaction that it is really possible to remove
all partition reading code from the kernel and do
everything in userspace. Maybe he is the first to actually use
these facilities. However, not everything that is possible
is also convenient - when these facilities really get used, it
will probably be a good idea to add a little more kernel stuff.]
[Something else that is possible today, but used by nobody,
is to have a Linux disklabel on a disk, with first a label
for the disk itself and then a list of partitions and volume
labels for each, independent of the filesystem inside the
partition. I have not really thought about what would be
the most elegant or the most convenient way to make such
things available.]
