This update should simply replace the system.img that is in /opt/alien currently, and that in turn could fix logd without needing to complete your rollback.
Amazingly (to me anyway) it has. Both /system/bin/logcat and
lxc-attach -n aliendalvik – /system/bin/logcat are now working.
Spoofing went but ln -s /home/defaultuser /home/nemo alone fixed it.
Either AD 9 or default system.img allowed me to set up a Google account for Android too.
