Description Christian Glombek 2022-07-25 06:18:21 UTC 
Description of problem:

In OKD/FCOS, there is no reason from a supportability standpoint to
enforce an allowlist for kernel arguments that the MCD can tune.
Currently, its existence is actually rather a hindrance, as in OKD this
API is used to set kargs during cluster bootstrapping via manifests,
the flexibility of which is therefore limited.

Solution: Drop the allowlist when running on FCOS

Version-Release number of MCO (Machine Config Operator) (if applicable): 4.12

Platform (AWS, VSphere, Metal, etc.): n/a
