Thanks, that's appreciated!
* As defined in the Ansible defaults the temp dir for building the local HE VM is

You can affect this via the ansible var he_local_vm_dir_path . I don't
think we have this documented anywhere, or even whether that's easily
settable by the user.
* Permissive umask required. Our CIS CentOS 7 build requires that default umask is 027.
This breaks the installer as it creates the VM image under /var/tmp as root and cannot
then access it as qemu user. As the temp files are cleaned up on failure it took me a
while to track this one down. My solution was to temporarily set the umask to 022 for the
session while running the installer. It would be nice if the installer either handled this
by doing a chmod/chown as required, or at least doing a umask pre-check and failing with a
* SSH root login required on host. Again for CIS we have "PermitRoologin no"
configured in sshd. This means the add host task fails on the Engine, but instead of a
hard failure we get a timeout on the installer. Which left me chasing some imagined
routing/bridging/DNS issue. Eventually I realised I could get to the engine logs and found
the issue but took several hours. Would be nice if the installer could either support a
sudo option or at least perform a root login pre-check and fail with a meaningful error.
Also both of these make sense. Would you like to open RFE bugs to
track these issues?
For latter, we had in the past:
Perhaps you can reopen, to show your interest, although the details
have changed since then, as we now use ansible (in 4.4, fully. In 4.3,
