One of the annoyances of Linux is working out where configuration information is, following through multiple layers of indirection and files over-riding other files. This looks like adding another layer, another place to look, and if you're reading the man file for a shell (for example) it probably won't even mention that this could invalidate the information contained in that in the man file.

Generally, good behaved applications have an entry in their man page that spells out these details for you, so you don't have to work out anything.

Unfortunately so many packages these days don’t even have a man page at all let alone one with good config info.

You're not wrong. In a worst case scenario I resort to using strace to figure out where a program is reading config from.. from what I understand, if this kernel module is in use then even that approach wouldn't help.

But since the use case is personal dotfiles, I imagine the user isn't going to forget that they set this up.

To be fair the author shows an example of using NixOS. It's absolutely another layer of indirection (probably several) but it does make that usual Linux "fun" less problematic because of its immutable nature and API design.

No, it doesn't. The point of modetc is precisely keep both myself and the programs happy: the files are actually stored where I like to keep them, but they can be accessed as if they were stored where the developer intended.

Tomorrow: modify man pages from kernel space!

Always check the man pages..

And I said that the man pages would be a part of what you have to examine. 95 pages in the case of bash (that's after running it through troff). man pages were fine when they were three pages long, but their lack of any internal index has become a problem.

Ok, now you might have a dozen files which could contain the information, where the location of each file can be modified by environment variables. It's tolerable if you are working on something you change weekly, but a practical problem if you do it yearly or it's entirely new.
