Anyway, I like(d) Linux because it didn't had a splash screen and used

technical details from users).
Yes, I like those days too, but as you say, times are changing, and we
must adapt.
Of course, times are changing, including the amount of stuff printed on
screen. But I still find it much much easier to grep on the output of
dmesg than to search through thousands files in sysfs. Even if that can
be done with grep too (kind of). But it's much more complicated because
grep doesn't connect the file name with the content, so you need more
complicated stuff to combine both in order to search for and find
something in sysfs.
Come on, it's not that more complex. If you know the name of the file,
just do:
find /sys -print -name <name> -exec cat {} \;
And you'll get the data you want.
Basically, what you are saying is "printk is more convenient for me and
I do not care about the other cases that make much more sense with
sysfs". The kernel does not work that way.
No. First I don't know the name of one of the thousands file in sysfs,
just like I don't know all the possible kernel messages.
And second I still believe that KISS is the right way and frameworks
aren't the right choice for everything.
But because I still don't refuse to learn, I will attach the output of
find /sys -type f -print -exec cat {} \;
to future bug reports instead of the output of dmesg.
