              to separate the other references.

                 option is used.  Remove unnecessarily specific
                 details about where the cryptsource and crypttarget

                                       and crypttarget environment
                                       variables are not used if the

                                       Remove unnecessarily specific
                                       details about where the
                                       cryptsource and crypttarget

                                       be either initramfs-tools or
                                       dracut.
