Bug Description
Hi!
I have Ironic Zed version and try to use DHCP-less ramdisk booting with network data from config drive.
I use simple-init element, and deployment works fine for me. It creates and boots target image with 4 partitions (BSP,ESP,OS and config drive).
After that, no other actions are possible with server - next boot of ironic-python-agent ISO gets 2 config-drives and fails to get correct one.
[root@server devuser]# blkid -t LABEL="config-2"
/dev/sr: UUID="2023-
/dev/nume8n1p4: UUID="2823-
"config-2" TYPE="is09660" PARTUUID=
This happens because simple-init (glean) uses the same LABEL for config-drive, as an openstack config-drive of target image.
No possible workaround found.

We've discussed this issue during and after our weekly meeting, and that's the solution we're leaning towards:
1) Modify Glean [1] to optionally accept a hint for the IPA's configdrive in a new kernel parameter, e.g. glean-configdri
2) Modify Ironic's ISO building process [2] to generate a random label, e.g. config-<something> and pass it to Glean. This is going to be a breaking change, so we need to add it behind a flag with the intention to make it the default later.
