soft restart of a jail

[Michael Grimm]

Hi —

I recently migrated regular jails to VNET jails, and I am pretty much pleased about their new opportunities.

During that exercise I ran across the sysutils/iocage jail managment system, where I first read about a feature called "soft restart of a jail". If I understand it correctly, here one doesn't remove/start a jail including its network stack, but one only restarts a jail's "content", instead.

I did try to understand iocage's code, but I am unsure whether I got it right: previously defined routing is removed, followed by a /bin/sh /etc/rc.shutdown and /bin/sh /etc/rc, and finalized by a reimplementation of a previously removed routing. (I hope that I got that right.)

Here my question: wouldn't a "/bin/sh /etc/rc.shutdown ; /bin/sh /etc/rc" be sufficient? Is it necessary to remove/reinstall routing as well?

Again: I might be completely misunderstandig the code of iocage, thus my questions to those with more knowledge.

Thanks and regards,
Michael
