From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Are there any things in Linux that need to be started over from scratch? (lemmy.ca)

I'm curious how software can be created and evolve over time. I'm afraid that at some point, we'll realize there are issues with the software we're using that can only be remedied by massive changes or a complete rewrite.

Are there any instances of this happening? Where something is designed with a flaw that doesn't get realized until much later, necessitating scrapping the whole thing and starting from scratch?

And why "Permission denied" is bad reporting?

Because if a program dies and just prints strerror(errno) it just gives me "Permission denied" without any detail on which operation had permissions denied to do what. So basically I have not enough information to fix the issue or in many cases even to reproduce it.

It may just not print anything at all. This is logging issue, not "C based assumption". I wouldn't be surprised if you will call "403 Forbidden" a "C based assumtion" too.

But since we are talking about local program, competent sysadmin can strace program. It will print arguments and error codes.
