Yes, but it does warn you about it if there is a mismatch, and I
still think it's much safer (and will reduce bogus bug reports, not
that the recent bug reports have been bogus :-)) to build vinum into
the kernel with all the flak flying around.
I agree re: fixing the debugging support, but I don't think that should
be a priority. The priority should be to make vinum as reliable as
possible considering the number of people who are using it or will be
using it. Despite the problems, vinum is well on its way to
becoming a defacto standard for FreeBSD systems and for that reason
any perceived problem with vinum will become a problem with 'FreeBSD',
just like problems with NFS were attributed as being problems with
FreeBSD in past years (reviews, performance tests, etc.).
One of the main reasons FreeBSD has a better reputation for reliably then
Linux, for example, is due to our focus on testing whole (fully
integrated) systems over Linux's piecemeal approach. Vinum is now
a defacto part of that integration.
