Re: Upgrading bootblocks
Ive followed that and done boot0cfg -B ad1s1 and even boot0cfg -B ad1 but i still get: disklabel: Warning, old bootblocks detected, install new bootblocks & reinstall the disklabel when i do disklabel /dev/ad1s1 but I dont get the error when I do disklabel /dev/ad1 disklabel should definately be on ad1s1 as there are some non-bsd partitions on ad1 Petr Gergo Szakal wrote On Tue, 06 Feb 2007 14:21:02 +1100 Petr Janda <[EMAIL PROTECTED]> wrote: Im trying to edit a disklabel of an old DF instalation, but I get an error: disklabel: Will not overwrite old bootblocks w/ label, install new boot blocks first! How do I install new boot blocks? Petr Is this helpful? http://www.dragonflybsd.org/cgi-bin/cvsweb.cgi/~checkout~/src/nrelease/root/README

Any chance this extremely useful program gets imported into contrib? I'd be great to have it around all the time. The one I suggested 16 hours earlier is its successor, scan_ufs (in NetBSD). That's probably what should get imported, at least out into pkgsrc so that more systems can use it. --- Dmitri Nikulin Centre for Synchrotron Science Monash University Victoria 3800, Australia

Petr http://mail-index.netbsd.org/tech-userlevel/2005/07/29/.html Pretty much exactly what you ask for. Don't see why it shouldn't work with DragonFly too. That was a long time ago so you may as well do a checkout from the netbsd-4 branch now. Maybe this could be trivially ported to DragonFly, or pulled out into pkgsrc for other platforms to use. --- Dmitri Nikulin Centre for Synchrotron Science Monash University Victoria 3800, Australia
