This page has not been updated (yet) to reflect that support for all 3 job types (service, batch, system) which shipped in 0.9.2.
The current page implies that preemption is only available for system jobs.
This is early preparation for Nomad 0.12, where we plan to move Preemption from Enterprise feature suite to OSS for all.

* update `restart` documentation
#7288 added support for task-specific `restart` policy. this PR updates the docs to reflect that.
* added an explicit example of task-specific restart policy
* Update website/pages/docs/job-specification/restart.mdx
Follow-up for a method missed in the refactor for #7688. The
`volAndPluginLookup` method is only ever called from the server's `CSI`
RPC and never the `ClientCSI` RPC, so move it into that scope.
The current design of `ClientCSI` RPC requires that callers in the
server know about the free-standing `nodeForControllerPlugin`
function. This makes it difficult to send `ClientCSI` RPC messages
from subpackages of `nomad` and adds a bunch of boilerplate to every
server-side caller of a controller RPC.
This changeset makes it so that the `ClientCSI` RPCs will populate and
validate the controller's client node ID if it hasn't been passed by
the caller, centralizing the logic of picking and validating
controller targets into the `nomad.ClientCSI` struct.
task shutdown_delay will currently only run if there are registered
services for the task. This implementation detail isn't explicity stated
anywhere and is defined outside of the service stanza.
This change moves shutdown_delay to be evaluated after prekill hooks are
run, outside of any task runner hooks.
just use time.sleep
Before, the submitted jobspec for sidecar_task would pass
through 2 key validation steps - once for the subset specific
to connect sidecar task definitions, and once again for the set
of normal task definition where the task would actually get
unmarshalled.
The valid keys for the normal task definition did not include
"name", which is supposed to be configurable for the sidecar
task. To fix this, just eliminate the double validation step,
and instead pass-in the correct set of keys to validate against
to the one generic task parser.
Fixes#7680
Before, if the sidecar_service stanza of a connect enabled service
was missing, the job submission would cause a panic in the nomad
agent. Since the panic was happening in the API handler the agent
itself continued running, but this change will the condition more
gracefully.
By fixing the `Copy` method, the API handler now returns the proper
error.

Use go mod for github.com/hashicorp/go-bindata/go-bindata and
github.com/elazarl/go-bindata-assetfs/go-bindata-assetfs but use
`@master` to pull the latest master. These packages don't have release
tags so `@master` worksaround it.
