		rgrimesAuthorUnsubmitted Not Done Inline Actions please do make this exit_rebootloop, no doubts in my mind now as to what is going on here, and that this should not be called passthrough due to confusion factor. rgrimes: please do make this exit_rebootloop, no doubts in my mind now as to what is going on here, and…

		rgrimesAuthorUnsubmitted Not Done Inline Actions Man pages sayes this is reboot, not sure what the differences are yet. I believe it is actually reset, and you have to do the reboot externally by re running the bhyve(8) command. rgrimes: Man pages sayes this is reboot, not sure what the differences are yet.

		rgrimesAuthorUnsubmitted Not Done Inline Actions The only case that this new code would trigger on would be if the bhyve exit code is 0, and -x was specified. How does that add any exit information? Furthermore that would break the reboot while [ 1 ] loop, is that what your trying to achive? rgrimes: The only case that this new code would trigger on would be if the bhyve exit code is 0, and -x…
		rgrimesAuthorUnsubmitted Not Done Inline Actions Adding a note, to above, yes this is trying to break the reboot while [1] loop, ie you want to manage reboots in a loop outside bhyve(8). rgrimes: Adding a note, to above, yes this is trying to break the reboot while [1] loop, ie you want to…
		jhbUnsubmitted Not Done Inline Actions And, since the script uses 'exit $bhyve_exit' it does pass through a different exit value to the caller when -x is used (the caller would never see 0 otherwise). jhb: And, since the script uses 'exit $bhyve_exit' it does pass through a different exit value to…
