Lab 10.1
Hi,
I have been pulling my hair out trying to get this to work correctly during the last 2 days!
Everything in Lab 10.1 works fine until the reboot at the end and it then all falls apart.
Admittedly, I changed the encrypted directory from being on the root directory to being a directory off my home directory. Should that make a difference?
Problem symptoms:
I get prompted 3 times (!) to enter the encryption passphrase on boot.
Along with the passphrase prompt I get the following message:
"The disk drive for /home//.secret is not ready yet or not present. Continue to wait. Press S to skip mounting or M for manual recovery."
After entering the passphrase three times as prompted I am obliged to Press S to skip mount and continue boot.
Does anyone have any bright ideas about how to solve this?

1) your /etc/crypttab line looks wrong. You have two device nodes instead of something like
secret-disk /dev/sda4
as in the lab solution.
2) I assume in your /etc/fstab you put in a real username instead of <username>
3) I assume /home/yourname/.secret exists as a directory (usually empty)0 -
Hi Jerry,
I edited /etc/crypttab as suggested and its working.
I did take a look at the Ubuntu crypttab manpage
I don't know why the following was not clear...
The first field, target, describes the mapped device name. It must be a
plain file name without any directory components. A mapped device which
encrypts/decrypts data to/from the source device will be created at
/dev/mapper/target by cryptsetup.
...but I do remember being indignant that a target would come before a source in the configuration parameters. For as long as I can remember source has always come before target. I am probably being a pompous old fart but this seems to be the equivalent of bad grammar.
Anyway, thanks for you assistance.0
