How to auto-mount a copied encrypted home
- by LedZ
How can I auto-mount and use my encrypted home that I copied to another partition on the same hard disk?
I'm running Ubuntu 11.10. My encrypted home is on sda1. There I've 2 users: userA and userB. Another partition is sda3 on which I have some other Data. BTW, sda1 is formatted as EXT4, sda3 is formatted as EXT3.
I did the following:
I logged out from GUI (Gnome) and changed (using Ctrl+Alt+F1) to the shell. From there I logged in, changed to sudo (using sudo -s) . After then I
created a new mountpoint (tmp) under /mnt (mkdir /mnt/tmp)
mounted /dev/sda3 on that mountpoint /mnt/tmp (mount /dev/sda3 /mnt/tmp)
copied my encrypted /home to /mnt/tmp using rsync
(rsync --acvxASXH --progress --stats /home/ /mnt/tmp/).
After the “copy-procedure” I looked to my “new home” in /mnt/tmp and there I found the following 3 folders:
userA,
userB,
.ecryptfs
My structure for /dev/sda3 mounted on /mnt/tmp looks like the following (userB in ecryptfs I've not listed):
-userA
¦
+userB
¦
+.ecryptfs
¦
+userA
¦ + auto-mount
¦ + auto-umount
¦ + Private.mnt
¦ + Private.sig
¦ + wrapped-passphrase
¦ + .wrapped-passphrase.recorded
¦
+ .Private
+ (encrypted file_1)
+ (encrypted file_2)
+ (encrypted file_n)
Now I would like that this copy of the original home-directory should act with the same behavior as the original home-directory means, that it should be auto-mounted at reboot and give me access to my unencrypted files and after logout all my files should be encrypted again. Any suggestions?
