So this is not a bug. That may be, but how was I supposed to know this? It doesn't seem to be documented anywhere. How would a regular user, without intimate knowledge of the Debian system and organisation find this out, other than the hard way? If it is unsupported then why do the lvm tools try it anyway, knowing that the system will crash? A two-line patch to lvmcreate that checks the kernel version would do the job, but the lvm2 maintainer says in #375116 that "it's really not userspace's task to check that the kernel is not buggy". What about the general rule that partial upgrades should be possible (e.g., upgrading the kernel without upgrading lvm2)? This bug may not be terribly important by itself, but the combination of LVM-related bugs that I originally reported form a subtle trap from which I think ordinary users will find it very difficult to escape, if they can at all. -- Sam Morris http://robots.org.uk/ PGP key id 1024D/5EA01078 3412 EA18 1277 354B 991B C869 B219 7FDB 5EA0 1078
