in less than 5 posts, someone will link to a 0pointer.de page that will explain you why you're doing it wrong since years.

remove ASK or replace it with "none".

Also...

See crypttab(5)

Ok, I'll bite what was he doing wrong?
Note, I have encrypted disks but my crypttab is all commented out... (Am I doing it wrong?!)

I think bangkok_manouel is just talking nonsense (but correct me if I'm wrong). As far as I know there was nothing very wrong with the old crypttab format (I had some minor gripes, but nothing worth worrying about). It was simply unnecessarily different from what all the other distros were doing, so we try to encourage people to use a cross-distro format (based on what Debian originally did). It is documented in the crypttab manpage.

i found the problem. thanks for everything. no more legacy message.

devil_kc, just be fair. Please tell us what the problem was (even if it was only an oversight) so that others can profit from this.

devil_kc · 2012-08-06 06:51:33

sorry, i replaced "ASK" with "none" in crypttab and now there are no more notifications.

upuaut · 2012-08-13 14:52:36

Please excuse my late delivery ;-)

but I have the same error than devil_kc but my /etc/crypttab looks different.

swap /dev/sda7 SWAP -c aes-xts-plain -h whirlpool -s 512
home /dev/sda6 /crypto/home.key

I take a look at crypttab(5) but I am apparently too stupid

Thanks for your help!

Hi,

I have only just encountered this issue myself, so apologies for the late reply.

I found the /etc/crypttab config had been updated but added to the system as /etc/crypttab.pacnew (leaving the existing one in place). See here for more info on pacnew files: Pacnew and Pacsave Files

I noted my edits from the original config, and then replaced it with the new config file. I then added my configurations back in, however, I think that swap entry used is no longer valid.

I had previously been using the same line as you but but found that the example given in the new config file stops the "legacy crypttab format" warning.

Swap example is:

# swap /dev/hdx4 /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256

Here is some more info I found that may be useful: http://archlinux.2023198.n4.nabble.com/ … 58466.html

Hope that helps.

Thanks a lot.
The new swap example worked for me.
