Upgrading libc6 causing a new xe-daemon process to be spawned

[Kevin Xu]

Steps to reproduce the issue:

$ ps aux | grep xe-daemon
root 803 0.0 0.0 4440 692 ? Ss 14:41 0:00 /bin/sh /usr/sbin/xe-daemon
root 2574 0.0 0.0 11740 940 pts/2 S+ 14:46 0:00 grep --color=auto xe-daemon

$ status xe-daemon
xe-daemon start/running, process 803

$ ps aux | grep xe-daemon
root 803 0.0 0.0 4440 692 ? Ss 14:41 0:00 /bin/sh /usr/sbin/xe-daemon
root 3258 0.0 0.0 4444 652 ? Ss 14:47 0:00 /bin/sh /usr/sbin/xe-daemon
root 3626 0.0 0.0 11748 920 pts/2 S+ 14:48 0:00 grep --color=auto xe-daemon

$ status xe-daemon
xe-daemon start/running, process 3258

It causes the system reboot to stuck, maybe due to it stuck on killing the remaining xe-daemon.
