Modify zfs-mount-generator to produce a dependency on new zfs-import-key-*.service units, dynamically created at boot to call zfs load-key for the encryption root, before attempting to mount any encrypted datasets. These units are created by zfs-mount-generator, and RequiresMountsFor on the keyfile, if present, or call systemd-ask-password if a passphrase is requested. This patch includes suggestions from @Fabian-Gruenbichler, @ryanjaeb and @rlaager, as well an adaptation of @rlaager's script to retry on incorrect password entry.

README
Shell scripts are the recommended choice for ZEDLETs that mostly call other utilities and do relatively little data manipulation. Shell scripts MUST work on both bash and dash. Shell scripts MUST run cleanly through ShellCheck: http://www.shellcheck.net/ General functions reside in "zed-functions.sh". Use them where applicable. Additional references that may be of use: Google Shell Style Guide https://github.com/google/styleguide/blob/gh-pages/shell.xml Dash as /bin/sh https://wiki.ubuntu.com/DashAsBinSh Common shell script mistakes http://www.pixelbeat.org/programming/shell_script_mistakes.html Filenames and Pathnames in Shell: How to do it Correctly http://www.dwheeler.com/essays/filenames-in-shell.html Autoconf: Portable Shell Programming https://www.gnu.org/software/autoconf/manual/autoconf.html#Portable-Shell Please BE CONSISTENT with the existing style, check for errors, minimize dependencies where possible, try to be portable, and comment anything non-obvious.
