features:
- Added the possibility to give root device hints
for nodes, covering the same type of hints as
Ironic allows.
deprecations:
- Currently only support for disk size hint was possible
on OOOQ. This was using the ``disk_root_device_size``
setting, as well as the disk property on instackenv.json
This feature is not being removed, but the usage of new
root device hintes feature is prefered. If some device
hints are given using this new env setting, the old
way will be ignored.
In the future, ``disk_root_device_size`` hint will need
to be deprecated.
fixes:
- Currently OOOQ deploys on baremetal, on servers with multiple
disks, is not behaving correctly. There was the possibility
of giving root device hints, but only based on size. On systems
where the disk size was the same, it was impossible to target
the right disk.
