Hi.

I know that currently the support of Zabbix agent 2 is experimental and it is supported in Linux platform only.

Just want to check if there is a plan to support others OS platforms.

Our Go expert on FreeBSD ports looked into, and for building Agent 2 on FreeBSD, there are some tweaks to be made.

• Change hardcoded paths for _linux.go.
• Replace syscall package which is not portable, for golang.org/x/sys/unix instead

These are the changes that were made, maybe it helps.

This was just a test, others parts will need changes as well.
