That's why I suggested IP cameras earlier, as there is no driver.  Or,
figuratively speaking, the IP stack is the driver.  Anything can break
after an update, but basic networking functionality is one of those
things I don't expect to break.

Also, why are you doing updates anyway?  If you had an appliance, as
you wanted, would you be doing updates on that?  Probably not, if it's
working.  So why worry about updates?  Put ZM on a dedicated server or
VM, get it working the way you want, then leave it alone.  Weld the
case shut and disable remote logins and now you literally have an

My personal experience with lower-end hardware is that it's the stuff
most likely to break during updates.  It's cheap so the release
process is sloppy and documentation
lagging/poor/inaccurate/non-existent, so you end up with situations
where the drivers are chasing infinite subtle revisions, and/or
reverse engineered, and/or some other kind of kludgery.

If you pay a premium, you can buy stuff that has official Linux
support from the manufacturer.  I was looking at Sensoray products for
my home, but they are out of my price range.  Probably beyond your
budget as well (based on what you've suggested), but it appears that
Linux is an explicit target for their products, not an afterthought or
the dreaded unsupported/use-at-your-own-risk.

But again, IP cameras remove all this complexity
