there's a rather complex set of interdependencies between linux-image-2.6.39, libdevmapper, initramfs-tools and LVM that has resulted in a system which last had 2.6.32-trunk-amd64 installed (and associated packages) failing to boot when the latest 2.6.39 kernel was installed. the root filesystem is on an LVM partition. the error that occurred will be familiar to anyone who has done kernel development especially embedded linux development: unable to find root filesystem, after only about 5-10 lines of kernel messages. it's incredibly early on in the boot process, and is probably in the initial ramdisk stuff, when looking for (duh) the root filesystem. the *only* thing that was installed, which resulted in the boot failure, was the linux 2.6.39 kernel. this, obviously, triggered an initrd build (but not of the 2.6.32 one, i don't recall seeing that: could be wrong though). now, i've discussed this on the bugtracker and there clearly isn't - and really shouldn't be - a listed debian dependency between linux-image-2.6.39 kernel and a userspace library. however, there clearly *is* a dependency because "It Don't Wurk (tm)". so the issue is: how the bloody hell should this clear dependency be expressed in "Debian Dependency" terms, such that nobody else runs smack into this same issue? ben's suggested that there may be something in initramfs-tools that's up the creek. however, i'm having difficulty finding a link (depends, rdepends) between libdevmapper and initramfs-tools (which may in fact be the issue). are there any other ideas on how this may be resolved? l. p.s. here is a list of reverse-dependencies of libdevmapper, and dependencies of initramfs-tools (and a few more). not going significantly into any depth here [wookey, where's that visualisation graph system you were working on! :) ] it's hard to find a link between initramfs-tools which *explicitly* mentions "LVM2" and any lvm2 packages in any initramfs-tools dependencies. beh? lkcl@teenymac:~$ apt-cache rdepends libdevmapper1.02.1 libdevmapper1.02.1 Reverse Depends: initscripts udisks parted libparted1.8-12 libparted0debian1 udisks initscripts parted libparted0debian1 multipath-tools kpartx lvm2 liblvm2cmd2.02 liblvm2app2.2 libdevmapper-dev dmsetup clvm lilo python-libvirt libvirt0 libvirt-bin grub-pc-bin grub-emu grub-common eject libdmraid1.0.0.rc16 libcryptsetup1 cryptmount initscripts libparted1.8-10 multipath-tools kpartx lvm2 clvm lilo eject dmraid libdevmapper-dev dmsetup cryptsetup cryptmount Package: initramfs-tools Version: 0.99 Depends: klibc-utils (>= 1.5.9-1), cpio, module-init-tools, udev (>= 0.086-1), findutils (>= 4.2.24) Recommends: busybox (>= 1:1.01-3) | busybox-initramfs Package: udev Version: 0.125-7+lenny3 Depends: libc6 (>= 2.7-1), libselinux1 (>= 2.0.59), libvolume-id0 (>= 0.113-1~), lsb-base (>= 3.0-6) Pre-Depends: debconf (>= 1.4.69) | debconf-2.0 Conflicts: hal (<< 0.5.6-2), hotplug, initramfs-tools (<< 0.39), initscripts (<< 2.85-16), klibc-utils (<= 1.4.19-1), lvm-common (<< 1.5.13), makedev (<< 2.3.1-80), module-init-tools (<< 3.2.2-1), multipath-tools (<< 0.4.7-2) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
