It's nice getting a glimpse as to what fraction of Linux users are using disk encryption. Full disk encryption is becoming the default on mainstream OSes, but not in most of the Linux installers I've encountered. Always made me curious just how many people went out of their way to encrypt their Linux install.
I personally encrypt everything except for VMs already in an encrypted device or USB drives that need to work with non-Linux machines. It'd be interesting to hear what other people's reasons to encrypt their disks or not are.
