I have some encrypted disks within my machine and I'd like to boot up and only type one passwd into stdin. Unfortunatly root encryption is not feasable as I use a SSD for that and 3.1 did not hit the stable repo yet (which introduces discard forwarding through dm-crypt containers) (I need that stability for my daily work, and data-loss is a total no-go).
So my thought is to make a filechunk of 100MB with ext4 and map it to /etc when entering a password on bootup.
Pretty much the same procedure as encrypted root. For my understanding, this either requires some custom hack and/or double readings of /etc/crypttab to be effective (once the one locate on the root fs in directory etc, and once the actual one with the remaining mappings from the one located within the container).
I also would appreciate to keep all actual config data within the encrypted container.
Did anyone ever try something like this? Any results?
Thank you
Regards

You could consider using a patched version of wiper.sh to TRIM your disk until 3.1 is released...
Can't help WRT encryption and your original question.
