Haven't looked this multipath issue now all up. But i remembered it was you who has interest in multipath support inside debian-installer and so grub2 too. I'm a bit unsure if I should just merge this with 483971 or reassign at GRUB Legacy, where the dummy grub package still is, and add a debconf note that gets shown when multipath is detected and tells people to keep Legacy for now. But it still looks like that you're the only one for whom multipath is important.

Hi Felix, Thanks for the quick response. On Sat, Nov 21, 2009 at 07:04:42PM +0100, Felix Zielcke wrote: > Looks like you forgot about 483971 and 442382. > and maybe even others.

This one is different as it breaks upgrades from existing and supported installations. > I'm a bit unsure if I should just merge this with 483971 or reassign at > GRUB Legacy, where the dummy grub package still is, and add a debconf > note that gets shown when multipath is detected and tells people to keep > Legacy for now. That would at least be a workaround. > But it still looks like that you're the only one for whom multipath is > important.

Multipath is run in "enterprise" environments where people are much more conservative regarding upgrades. I'm starting to get reports from etch->lenny upgrades so don't expect many others to notice within the next year.

The older ones were reassigned to grub-common and you filed this against grub-common (actually even grub-probe). If it's more important then wishlist then the severity of that bug needs to be changed and not a new one filed which exactly says the same: to implement multipath support inside grub-probe. > > I'm a bit unsure if I should just merge this with 483971 or reassign > at > > GRUB Legacy, where the dummy grub package still is, and add a > debconf > > note that gets shown when multipath is detected and tells people to > keep > > Legacy for now. > That would at least be a workaround. > > > But it still looks like that you're the only one for whom multipath > is > > important.

The debian-testing mailing list were all upgrade-reports end doestn't say anything about multipath back to 2008/12. -- Felix Zielcke Proud Debian Maintainer and GNU GRUB developer -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
