Err, no. As someone else has already noted, a prominent KLM that's distributed separately from the kernel which uses the vnode structure extensively (which I didn't think of at all until I read the respective mail) is fuse. A pre-upgrade compiled fuse is most certainly going to break because of this change. Some people have dual installations of Windows/FreeBSD (at least I'd presume that's the case with the fiddlers like me that track -STABLE as a hobby, not as a developer, or those developers who program for Windows as a day-job, also like me) who use ntfs-3g to mount their NTFS-data; additionally, I also extensively use ssh-fs, which is also fuse-based, and I guess there are also others who use it, and so the reach of this ABI-change, at least IMHO, is much larger than the original message makes you believe. Now, after the update, a lot can go wrong, because the fuse KLM is loaded by an init-script, and your system is most probably going to Oops while booting if you didn't think of disabling the fuse init-script before you update your kernel, and will NOT fail "gracefully". If the respective person doesn't know how he/she should boot to single-user-mode, update rc.conf to disable this, reboot, rebuild the module to get the system back up, the only thing I can possibly say is: "don't track stable." It might've sounded a bit harsh what I wrote, but tracking -STABLE means knowing your system enough so that you know how to fix things if they come back to bite you (especially after getting a HEADS UP). And that doesn't seem to be the case here if the respective person asks for SPECIFIC instructions what to do. So, again: DON'T track -STABLE if you can't fix the system if it breaks, and AFAICT this change is most certainly going to break quite a few systems. -- Heiko Wundram _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
