Public bug reported:
Binary package hint: cryptsetup
My /etc/crypttab contains the following disk which is not yet mapped:
$ cat /etc/crypttab
sdb_crypt /dev/sdb /keyfile luks
But the initscript won't process it:
$ sudo LC_ALL=C invoke-rc.d cryptdisks start
* Starting remaining crypto disks...
invoke-rc.d: initscript
cryptdisks, action "start" failed.
Debug output gave me the following:
$ sudo LC_ALL=C bash -x /etc/init.d/cryptdisks start
[ for the full output, see attached file "bash debug output" ]
[ ... ]
+ load_optimized_module
+ local module optmodule
+ module=
+++ uname -r
++ find /lib/modules/2.6.24-18-generic/kernel/arch -name '*.ko'
+ optmodule=
$
Here the script stops. I've investigated the code in
/lib/cryptsetup/cryptdisks.functions and noticed that the load_optimized_module
function takes the module that should be loaded as an argument, but is called
without any arguments in do_start (line 592 for me). I'm not entirely sure
where the module should come from, but simply removing the call did the trick
for me (aes_x86_64 was already loaded because I've a cryptroot).
$ LC_ALL=C apt-cache policy cryptsetup
