Do you really think listing your LFS as "unknown Linux distribution" is
not
a bug in itself ?


This is regression. Distribution was detected and bootable before update on
stable openSUSE version and is not detected after update. Whether or not
this behavior was correct to start with is subject to discussion but we need
to fix regression.

Honestly I do not concern the regression, I really want to put detecting and
booting unknown distribution to rest. We don't need any fallback here, if a
distro is undetected it's not listed.

I have old patch that avoids opening each file to get its size in
grub-mount. I'll try to see if it gives any improvements.

If it can be helpful, then we can determine to restore the behavior later.

But at the very least I would say we need to restore old check as fallback
branch if distribution was not explicitly detected.

Then we will get back regression of the slow down issue. The very critics
with os-prober is not all about its functionality, but spending great amount
of time stuck in running it, effectively hinders many people to accept it
(as the solution for multiboot).

As a user, I would say that a noticeable slowdown is an annoyance that I would
hope would be eliminated (though I would add that I did not notice any
difference in the speed of os-prober before and after the latest update, nor
did it strike me as slow before), but a (part of a) boot-loader that fails to
find a bootable system is not just an annoyance, it's useless.
