[Trisquel-users] File system encryption in Trisquel?

[b112327]

Hello,

in the current Ubuntu there is an option during the installation time to  
encrypt the filesystem on the harddrive. When you turn on the computer, after  
the BIOS loading, user have to enter his password to decrypt the file system  
and let the OS to boot. If the password is wrong then the OS won't load.

I really liked this option in Ubuntu and I miss it very much in Trisquel. Are  
there any ways to being this functionality into Trisquel?
