There is no code in kernel-source/init/do_mounts.c for mounting a filesystem by its UUID, however there is code for mounting a filesystem by that filesystem's partition's UUID.

Are there any technical limitations preventing root=UUID=<uuid> support from becoming a reality?

  • @JuliePelletier, it's not, because in my case, I know that the kernel does not support the filesystem's UUID because it doesn't have the code, I want to know why nobody has added that support yet. I want to know if there is something that's blocking people from adding that support. Because of that, the question you linked does not have an answer for my question.
