…as root Although nomad officially does not support running the client as a non-root user, doing so has been more or less possible with the raw_exec driver as long as you don't expect features to work like networking or running tasks as specific users. In the cgroups refactoring I bulldozed right over the special casing we had in place for raw_exec to continue working if the cgroups were unable to be created. This PR restores that behavior - you can now (as before) run the nomad client as a non-root user and make use of the raw_exec task driver.

Although nomad officially does not support running the client as a non-root
user, doing so has been more or less possible with the
raw_execdriver aslong as you don't expect features to work like networking or running tasks
as specific users. In the cgroups refactoring I bulldozed right over the
special casing we had in place for
raw_execto continue working if the cgroupswere unable to be created (on Linux). This PR restores that behavior - you can now
(as before) run the nomad client as a non-root user and make use of the
raw_exectask driver.No CL since this bug hadn't shipped yet
Note: this should fixup the vaultcompat tests in the ent repo
