Hello,
I'm testing the latest CentOS Atomic host rolling build (20150228_01).
Apparently the brctl command, as normally provided inside bridge-utils rpm package, is not present.
I can query 
/sys/class/net/docker0
and
/sys/class/net/veth*/
subtrees, but it would be nice to have it, unless superseded by another docker/atomic command...
Thanks in advance,

Gianluca

PS: I posted here because I'm not subscribed to atomic-devel too atm.. let me know if it's a problem
