[lxc-users] Possible bug

[Saint Michael]

On Ubuntu 16.04..2 LTS, kernel 4.4.0-78-generi

inside a container I erase the file /etc/mtab
the containers start, a new file /etc/mtab gets created
I stop the container,
I start the container
the line with tmpfs starts growing ad -infinitum, this way

tmpfs /run/shm tmpfs
rw,noexec,nosuid,nodev,size=17499420k,mode=1777,size=17499420k,mode=1777 0 0
tmpfs /run/shm tmpfs
rw,noexec,nosuid,nodev,size=17499420k,mode=1777,size=17499420k,mode=1777,size=17499420k,mode=1777
0 0

Note that each time I restart the container, the line gets a new size and
mode parameters, in spite the fact that they are  already there. After many
restarts, the kernel starts complaining

tmpfs: No value for mount option 's'
