Agree. You don't have directories named with random hex numbers. you 
simply know what is where.

While i've used jails a lot i recently use it rarely. Because i 
found that usually they are not needed. Standard unix protection 
mechanisms (processes, users, groups) are just fine. For example apache
runs just fine as user.

I completely don't understand why the fashionable microservices (which are 
not bad idea as they should have dependencies) needs jail-like 
environments, instead of simply running a process in a separate user account.

What is wrong in ALL systems today are shared libraries or languages 
(like python or perl) that depends on millions of files. Getting rid of 
them will make "microservice" idea the right way.

Simply having static executable to be run. Or multiple static executables 
communicating by pipes.

So "microservices" means rediscovering 1980-style (and earlier) way of 
writing programs. Rediscovering but with of course messy way.
