Ruined encrypted partition.

I've burned a LiveCD 9.04 alfa i386 daily build from 08/12/08 and booted my laptop from this CD. After this I rebooted my laptop, but now I can't mount encrypted /home partition - I enter right password, but have no luck... Why? I've booted from this CD again in hope of understanding what's wrong with my partition and now I see a problem. I have 3 partitions on my disk:

ubuntu@ubuntu:~$ sudo fdisk -l

Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x9a20f00c

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         765     6144831   83  Linux
/dev/sda2   *         766        5227    35840000    7  HPFS/NTFS
/dev/sda3            5228       14593    75232395   83  Linux

Where sda1 is my /root partition and sda3 is my encrypted /home partition. Yes, I have no swap (not using sleep or hibernate mode).

BUT look at this:

ubuntu@ubuntu:~$ free
             total       used       free     shared    buffers     cached
Mem:       2064464    1291720     772744          0     109044     650748
-/+ buffers/cache:     531928    1532536
**Swap**:      2498096          0    2498096

And at this:

ubuntu@ubuntu:~$ swapon -s
Filename				Type		Size	Used	Priority
**/dev/sda3**                               partition	2498096	0	-1

So, first time I boot JJ (like this time, too), my /home partition was mounted as swap and the result is on the thread name...

Thank God I have no unsaved valuable data on /home So, I do not advise to repeat my experiment with a similar partitioning of HDD, like I have (But I think it's some sort of rare partitioning ;)).

I checked the kernel GIT and it seems that support for encrypted partitions is coming

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-jaunty.git;a=summary

UBUNTU: Build ecryptfs into the kernel

Bug: #302870

Latest change....but I can be wrong..

Surely the problem here is that a liveCD is assigning a swap partition AT ALL. If I put a LiveCD into my machine and boot from it, without asking for any install of the OS, I DON'T expect it to write anything anywhere on my disk, do I?

I don't believe the problem lies with encryption, enabled or not. It's simply an egregious error in the LiveCD that it writes to the HD instead of keeping everything in RAM.

you are correct it is very bad that the live cd would make any changes to your system without being specificly told to infact it should run without even having a HD installed on the system. @fwhr file a bug on this one .

This is quite interesting too in that if it's a swap the type should have been 82 and looks like this

/dev/sda11          13377       23345    80075961   83  Linux
/dev/sda12          23346       24321     7839688+  82  Linux swap / Solaris

Sorry, I am not familiar with launchpad. What package/project I need to choose to report a bug?

I think you just visit https://launchpad.net/ubuntu/jaunty/ and click on "Report a Bug".

If you leave the package you are fileing the bug against as "I don't know" the person that triages the report will assign it to a package. just describe what happened as best you can . they will ask for more info if they need it.

This page from the wiki provides a few guidelines for selecting the proper package: https://wiki.ubuntu.com/Bugs/FindRightPackage

I think the relevant advice for your case is this:

If you encounter a bug when using the Live CD environment, not the install process, and there is no more obvious package to use (e.g. a particular application is failing), then the package used for the bug should be casper.
