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. -Matt Matthew Dillon : : Of course, I would not do this on a normal basis, just during the :current difficulties while certain bugs are tracked down and fixed. : :-- : These are my opinions -- not to be taken as official Skynet policy :====================================================================== :Brad Knowles, || Belgacom Skynet SA/NV To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
