<above the emacs debian-bug command output>

The exact and complete text of any error messages printed or logged:

# cryptdisks_start   sdb2_crypt
sdb2_crypt (starting).
Command failed: No key available with this passphrase


A description of the incorrect behaviour: exactly what behaviour
you were expecting, and what you observed.

attached /etc/crypttab file where you can see the "none" => interactive
passphrase.
After the "Command failed: No key..." message" the keyboard
locks (X-Windows system) and a reboot is needed (mouse does not lock).

The direct command "cryptsetup luksOpen /dev/sdb2 sdb2_crypt"
works perfectly, only the crypdisks_start script fails.

cryptdisks_stop sdb2_crypt script is successfull if runs after
"cryptsetup luksOpen /dev/sdb2 sdb2_crypt"



Suggested fix:

I do not know. Please let me know if you need some testing for your fixes.


Additional information:
After some reading of the documentation I have found the following
extrange things:

File:
/usr/share/doc/cryptsetup/README.Debian.gz

"If you are using udev, it might be a good idea to use the /dev/disk/by-label
links instead of /dev/sdg2 as the link will work no matter in which order the
media is inserted and detected."

/dev/disk/by-label ... on kernel 2.6.26.1 also are /dev/disk/by-id

but in  "/lib/cryptsetup/cryptdisks.functions"

	# parse UUID= symlinks
	if [ "${src#UUID=}" != "$src" ]; then
		src="/dev/disk/by-uuid/${src#UUID=}"
	elif [ "${src#LABEL=}" != "$src" ]; then
		src="/dev/disk/by-label/${src#LABEL=}"

UUID= and LABEL= sintaxes are not documented on man crypttab
There is also ID= ( /dev/disk/by-id on GNU/Linux kernel 2.6.26.1)

Maybe remove this sintax and use the full /dev path on all cases.




Thank you for your work and time.


Best regards
