Hi,

this may be a deliberate choice but I can't really figure out why one would make that decision...

[centos@atomic ~]$ sudo yum update
sudo: yum: command not found
[centos@atomic ~]$ rpm -ql yum | grep bin
/usr/bin/yum
[centos@atomic ~]$ ls -l /usr/bin/yum
ls: cannot access /usr/bin/yum: No such file or directory
[centos@atomic ~]$

I used the latest http://cloud.centos.org/centos/7/atomic/images/CentOS-Atomic-Host-7-GenericCloud.qcow2 in an RDO deploy. I don't experience the same issue with the regular image only with the Atomic.

regards,
  Bent
