GNU Pies – Program Invocation and Execution Supervisor

Almost 20 years ago now I worked for a company that sat a group of about 25 of us down to talk about their latest survey named...CRMPIES.

Everyone looked at me like I was insane as I sat there chuckling. Thank you for bringing back that unfortunate memory.

Everyone needs to have made a web framework. Everyone needs to have made a programming language. Everyone needs to have made a supervisor. Everyone has to have made a container manager. Everyone needs to have made a text editor.

One release every 4 years. So this is like monit or systemd-supervisord and so on, a process manager. I have to say the thing I most enjoy about it is the fact that it's got the classic GNU trend of "here's an obviously pronounceable spelling; let's say it a different way".

Are the collection of components run in some kind of namespace? Say I run a Pies for Gitlab (which in itself had lots of components), and I run a Pies for Frpd, do they share the same space or are they isolated from each other? Am I maybe overthinking this? Perhaps its just a program manager.

Is this the gnu version of systemd?

edit: I know it's not a monolith like systemd but service/unit files are a core component of systemd

> pronounced "p-yes"

Absolutely not.

Apologies to the Slavs, but there’s already a utility pronounced like that.

Pies it means "foot" in spanish

If you have to explain the pronunciation of the name of your tool in the first sentence, you've already lost.

systemd is not a monolith.

It's a collection of losely coupled components and services of which basically every single one can be disabled or replaced by another implementation.

The only thing missing is a recursive acronym e.g. Pies: Pies Is Experimental Software or something equally cringe like Hurd

Absolutely. I recently wrote my first compiler to get it off the bucket list… brainf*ck compiler/interpreter #100010134 or such? :-) Well… it was a fun half hour.

What's the value of making a supervisor? It seems to be mostly about gluing together some system APIs.

sudo? gnu? mate? debian? ubuntu? suse?

It's a collection of tightly-coupled components that are functionally a monolith because large distros tend to rely on the various components rather than allowing modularity.

"Pies" means "dog" in Polish an Ukrainian (пес).

Pies is eshewing systemd?

how about "Active Development" without any progress in 3 decades

"Pies" means "dog" in Polish an Ukrainian (пес).

So, "Gnu is Not Unix, Dawg"?

Is that pronounced “peace” or “piss”?

In some industries it’s critical. Think about aerospace where code is almost always homegrown or done by specialized company, and are specific implementations for specific needs. You don’t have that many COTS due to the criticality etc.

More like pi+[y]es, but single syllable and no y.

When do you use that vs собака (sobaka)?

I don't, I'm Polish. Can't say for sure for Ukrainians, don't know Ukrainian that well, but my reading of https://en.wiktionary.org/wiki/%D1%81%D0%BE%D0%B1%D0%B0%D0%B... and https://en.wiktionary.org/wiki/%D0%BF%D0%B5%D1%81#Ukrainian suggests that пес must be male, but собака is either male or female. I might be wrong.

The name Pies (pronounced "p-yes") stands for Program Invocation and Execution Supervisor. This utility starts and controls execution of external programs, called components. Each component is a stand-alone program, which is executed in the foreground. Upon startup, pies reads the list of components from its configuration file, starts them, and remains in the background, controlling their execution. If any of the components terminates, the default action of Pies is to restart it. However, it can also be programmed to perform a variety of another actions such as, e.g. sending mail notifications to the system administrator, invoking another external program, etc.

GNU pies can also be used as init daemon — the first process started during booting. The configuration can be supplied both as a traditional /etc/inittab file or as a native GNU pies configuration file, which gives much more flexibility. The control interface provides extensive monitoring and management capabilities.
