#3 x-zyx-0.6.0.1 has post-installed shutdown umount spewage

[Douglas McClendon]

There are seemingly harmless messages at the very end of the otherwise clean post-installed shutdown of x-zyx-0.6.0.1. These seem to be caused by the zyx-live service script being run unintentionally due to zyx-liveinstaller's failure to remove the zyx= parameter from the bootloader append string. A fix seems straightforward and should be available in git within a week or so.
