Environment variables

Install script

Variable	Effect
`DEACONGUARD_TOKEN`	Install an agent and enroll it with this token. The script passes it to setup through a private temporary file, never on a command line.
`DEACONGUARD_VERSION`	Install this release, for example `0.4.0`, instead of the latest.

Set them before sh, not before curl:

curl -fsSL https://get.deaconguard.io | DEACONGUARD_VERSION=0.4.0 DEACONGUARD_TOKEN=deaconguard1.… sh -

Variable	Effect
`DEACONGUARD_HOME`	The data directory. Default: `/var/lib/deaconguard` for the server service, `~/.local/share/deaconguard` otherwise.
`DEACONGUARD_AGENT_CONFIG`	The agent's configuration file. Default: `/etc/deaconguard/agent.json` for root.
`DEACONGUARD_TOKEN`	Read by `deaconguard setup agent` when no `--token-file` is given.
