Comment 3 for bug 651730

Cryptsetup is not installed by default and/or there is no visual indicator it is missing.

This are the problems user will encounter because of that:

-If encrypted USB media is inserted prompt for password will be shown but unlocking will fail.
-Disk Utility offers option when formating device to create encrypted volume and if selected formating will fail.
-Disk Utility does show encrypted media but an effort to unlock it will fail.
-...

Suggestion: cryptsetup should be available by default or visual indicator that it's needed but missing and needs to be installed should be presented!
