This change will still mount some useless stuff like:
{ "/.oldroot/proc/sys/net/ipv4", "/proc/sys/net/ipv4", NULL,
MS_BIND, false, false, true },
{ "/.oldroot/proc/sys/net/ipv6", "/proc/sys/net/ipv6", NULL,
MS_BIND, false, false, true },
You can set skipUserNS for these.
But I *really* would like to see /proc and /sys mounted RW as default.
Please see my comment to:
[PATCHv3] lxc: give RW access to /proc/sys/net/ipv[46] to containers
