Single Node Assisted Installer required node network to be at last /28

[JayDoubleu]

When trying to install single node OKD with Assisted Installer it returns below error:

Machine network CIDR xxx.xxx.xxx.xxx/29: Address mask size must be between 1 to 28 and must include at least 16 addresses
This error only seem to be appearing in version 4.8.17 while on 4.9.4 only returns non descriptive machine network CIDR : invalid CIDR address. I'm also unable to find documentation describing this requirement.

Is /28 definitely required when on single node cluster ?

I don't think Assisted Installer supports OKD (yet), at least we don't have 4.8.17 or 4.9.4 versions

Well google for "OKD single node" sent me to "https://docs.okd.io/latest/installing/installing_sno/install-sno-installing-sno.html"

I already installed it via assistant installer but on a larger subnet and seemed to work fine but doesnt seem to install OKD but trial version of OC.

I take it that the https://docs.okd.io/ is a copy of openshift docs meant to be modified for OKD ?

Is there any plan to bring assisted installer for OKD as well in coming releases?
