I wanted to mount an NFS disk in the LiveCD, so I tried a mount command; that didn't work. Turned out that the NFS support isn't even in the livecd, so I had to "apt-get install
nfs-common". This failed, even immediately after "apt-get update":
# apt-get install nfs-common

For those who run into this bug, which is caused by #882147, here is how to circumvent it while the boffins argue about what the right fix is.
Run "sudo initctl reload-
You may have to do this several times (each time it will enable one more system service, until you finally get the last one done).
The problem is that the system startup scripts depend on the kernel call "inotify" to tell them when a new startup script is added. However, inotify doesn't actually work when using an "overlayfs", which is how a LiveCD allows a temporary RAM filesystem to record temporary changes that are made to the booted read-only CD/DVD image.
