[Trisquel-users] Encrypted swap?

[tsduv1994]

Recently I had a problem with my home server. I found out because of this  
that there was no swap active on the system. I had a swap partition, but it  
wasn't mounted on boot. After much searching I found that the problem was  
that my swap partition couldn't be mounted because it contained an encrypted  
swap partition. This partition is called cryptswap1. I can't remember haven't  
ever made such a partition. Furthermore, it can't be mounted through fstab. I  
had to edit the local.rc file to be able to mount it.

More troublesome was the fact that I couldn't remove it. I tried everything I  
could think of to get rid of it. At first, I wiped the partition were it  
recided and recreated it. Upon boot up, cryptswap1 was back. So I deleted the  
partitions again (since the swap was in a logical) and made the rest of the  
hard drive primary. I proceeded by wiping that part of the hard drive using  
dd. Once I created the partitions again, cryptswap1 came back! I tried using  
dmsetup to clear it. It seemed to work, as dmsetup would no longer show it.  
Once I rebooted the machine, it came back! I then installed the package lvm2  
to try and use lvm tools, but the tools were unable to find any volumes! I  
searched on the Internet and it seems like it has something to do with  
choosing the option to encrypt the home directory. However, there's no  
cryptswap1 on my laptop and I accepted that option on this machine as well.

So, does anyone know why this is on my system? For the ones that chose to  
encrypt their home directories, is there a similar device under /dev/mapper  
for you?
