Michal,

 Now that you have sent a pull request to Linus, and therefore
addressed the main problem, may I dare to question your example ?

 I only started building kernels in (approximately) spring 2000, so I
am sure that I am missing a lot of history.  But /usr/src/linux*
smells of "tradition" in the Scots sense of "whit ma faither telt me
that his faither telt him" ("what my father told me that his father
told him" in english).  I am sure that /usr/src/linux might have been
an expectation in the distant past, but it tends to bring along the
assumption that kernels are _built_ by that dangerous guy called
'root'.

 Some of us (me included) often build things as root, but it has
many risks and people ought not to be led to believe it is
necessarily the correct way to do things.  Over the past 14 years I
have built kernels in ~/ as well as in other user-writable
directories and I am puzzled about why the idea of /usr/src/linux*
continues to exist.
