This picks up only one info file. Linuxrc supports multiple info arguments. Then it downloads and merges all info files.
This might be pretty useful. You can have a generic info file and an optional debugging one which additionally enables some debug features. This avoids duplicating the common parts between the info files. Just use the common one and if needed easily add the debugging one.

And linuxrc supports nested info files, you can use info= in info file as well... 😉

I know about both of those linuxrc features and it is possible to implement it, I just do not see much usage for it. What I see so far from bug reports is that there is just single info file param that contain required parameters. In the end there is not so much parameters you need to use and usually it is more like debug.info and if needed some production.info file.
I plan to document this limitation to old linuxrc behavior and if there is interest in extending it, we can always do it.

It also allow different locations not sure if the same supported by curl... so something to document too.

Problem
The linuxrc provides quite useful option to specify remote "info" file that contain additional parameters. It helps when kernel command line is restricted by amount of characters or if writing to it is annoying and it is better to point to that info file.
Solution
Implement support for
agama.info. Also implement filtering of agama specific kernel options and write it to/etc/agama/kernel.cmdline.confso yast2-bootloader can use it for proposal.Note: agama.info does not support all linuxrc info features like it quire correct name
agama.info=without any additional dots, dashes or different letter case. It also currently support only single info parameter and it cannot be recursive, so additional info parameters are not expanded. And last but not least it supports only url that is supported by curl.Testing
