The bug in lvm2 is that lvcreate allows the creation of the snapshot on kernel versions where it is known that the operation will crash the system. The bug in sarge's kernel is that the system hangs when a snapshot of a logical volume is created, that volume being used as the root filesystem. This bug is presumably present on other architectures as well as just i386. The bug in initrd-tools is that generated images don't include the dm-snapshot kernel module; if a system crashes or is rebooted while a snapshot LV is present, it will be unable to boot up. The bug in linux-2.6 is that removing a snapshot volume with the version of lvm2 present in sarge hangs the machine. This also breaks partial upgrades. The bug in initramfs is that the (already-included) dm-snapshot kernel module is not loaded when necessary. If a system crashes or is rebooted while a snapshot LV is present, it will be unable to boot up. -- Sam Morris http://robots.org.uk/ PGP key id 5EA01078 3412 EA18 1277 354B 991B C869 B219 7FDB 5EA0 1078 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
