I know, top posting....
Hi.
Other than the directory structure illustrated there, you've confused me. (Not
difficult!)
The problem I'm finding, is that everyone assumes everyone else knows what
everyone is talking about, in detail! I freely admit I don't! (But I'm slowly
learning.)
So.... Please excuse my ignorance, but what has "arena" got to do with Jails?
Bearing in mind, Ive yet to get any of this to work even in it's most basic form,
other than a base FBSD system that ticks allong nicely doing other things such
as NTP timekeeping duties.
The other thing is, I will be needing to document all this, so in x years time when
I might need to do it all again, I can. Though from what I'm hearing, it'll have
all changed again by then anyway, so I'll be back to square one.
Is there a simple (graphical) illustration with basic description somewhere, that
explain's how the parts of a jail inter-relate with each other, and the base
system? I'm a bear with a small brain BoBo! I'm doing this to support an
aspect of a hobby of mine, not for any proffit or gain.
Sorry, but there is just too much conflicting information to try and absorb at
present, and though I've been meddling with computers and other tech stuff for
many years (decades!) I'm a Unix noob in this respect.
Regards.
