I made the live system again with the latest packages on the Debian Sid,
so now systemd has been upgraded to version 226.
The time I have completely switch back to systemd, no more sysvinit with
"systemd-udevd" only.
With the same nfsroot architecture, the initial status of mounting
status in the nfsroot client is attached as "df-ok.txt" and "mount-ok.txt".
I actually did not run any Clonezilla job, just opened iceweasel to
browse youtuble in the nfsroot client.
Then again, the /tmp (tmpfs) is missing. The mounting status is attached
as "df-tmp-missing.txt" and "mount-tmp-missing.txt".
Any more info shall I provide?
Thanks.
Steven.
