Daemon not immediately available after start.

Hi,

I have taken over as maintainer for the tgt package (scsi-tgt) in Alpine Linux.

On Alpine we like to split packages to keep their footprint small. I have written an init script in two parts, one for the tgtd daemon and one for tgt-admin that loads the config file. I assume some people use tgtadm directly instead of tgt-admin and the config files.

I have one issue during launch of the tgtd, which is that it starts and returns ok to init system, which now tries to load the config via tgt-admin. This, however, sometimes fails. I saw that the same issue was documented in Gentoo, which solved the issue by adding a one second delay after starting tgtd, before issuing tgtadm or tgt-admin commands.

I think this is not an ideal situation as it is conceivable that an initiator tries to connect during that second, but finds an empty target.

Is there a good solution for this? 
* can tgtd wait until it is fully ready for connections from tgtadm before returning to shell/init system?
* or can tgtd start in offline mofd, and we can keep the one second delay before activating again via tgtadm?

Thanks,
