This extends run-cosmos with a new argument that calls the unlock
function already included in the script as well as using the already
existing lock() function to make sure there is no race between the
bootup process and cron starting a normal run-cosmos process at the same
time.
The oexit() function is added to support exiting with a OK exit value
the same way eexit() is used to signal something is wrong.
This change also adds the systemd unit file that runs run-cosmos with the
new fleetlock-unlock argument at boot if fleetlock is configured.
While here fix indentation that was mixed between 3 and 4 spaces: it is
now 4 spaces everywhere.
The db-file, essentially providing reverse lookup of classes to host
names, is only used by some Nagios configuration instances and causes
continuing operational headaches in those ops-repos.
It should be kept/refactored to only apply to the monitoring hosts in
the cases where it is used, but we don't want any new ops-repos to use
it hence it should be removed from upstream multiverse.
Before this change there was a need to keep addhost and
bootstrap-cosmos.sh in sync regarding what version of the cosmos deb to
scp over and later run.
Now we find the latest version as decided by `sort -V` in both addhost
and bootstrap-cosmos.sh.
Solution discussed with @fredrikt.
Good idea to fail when unexpected things go wrong. Additional fixes
added to the script to not stop where we can expect a non-zero return
code.
Requested by @fredrikt who also reviewed the patch before going in,
thanks!
