Package: cryptsetup Version: 2:1.0.6-6 Severity: critical Justification: breaks the whole system
Sometimes update-initramfs -v -k $kernelversion works and creates a file 'conf/conf.d/cryptroot' in it, as can be seen by unpacking it using gunzip and cpio; and in those cases, I can boot my laptop, which has its root fs on /dev/mapper/main-root which is a logical volume on a volume group consisting of a luks encrypted partition. In cases where I cannot boot, which manifests it in the system just doing nothing where otherwise it would ask for the passphrase, this file is missing. (Note: during bootup a message 'volume group "main" not found' is shown in both cases, this appears normal, I guess the scripts reattempt to find that one after the passphrase entering and associated crypto setup. It's just that in the bogus case, it never asks.) I did install the system using the capabilities of the Debian installer to create encrypted root partitions and LVM setups, and it worked for some time; probably the first occurrence of the problem was when I already started compiling and installing kernels manually (from kernel.org's Git, using make install and make modules_install), although this too worked upon the first (few?) kernel version(s). And, again, sometimes it still works, like when I installed 2.6.27.5 I could not reproduce the problem. This is also documented on a bug I reported against initramfs-tools, here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug= 503062 I've tried to reopen this bug but that does not seem to be possible? (Really?, how can we make people coming to that link know that the problem is *not* solved now? In an spell of amicability I'm creating such a link right now. "Google shall help them find out who linked to that report". Ok, I've now added two linebreaks to not make this happen.)
