1) Embedded systems often don't want man pages on the
target; rather than pointlessly building them, then ignoring
the result, allow just not building them at all
2) When bootstrapping an operating systems, documentation is the
source of many cyclical dependencies, and allowing it to
be explicitly disabled is useful for earlier build passes.
This was never documented in the manpage of module-init-tools either.
The flag is identical in function to modprobe's --dirname option, so use
the same language to describe it.
The documentation for this flag leads one to believe that the full path
to the module directory is needed. In reality, this flag specifies only
the root of the module path.
Only the public header maintains #ifndef in the header, together with
pragma. The other ones contain only pragma.
As reported by Shawn Landden on systemd mailing list this is compatible
with all major compilers and gcc has this since version 3.3.
We need to cope with the case in which a 32 bits machine is opening a 64
bits kernel module and vice-versa. The offset in `struct module' are
different and do not depend on the architecture we are running, but
rather on the architecture they were created for.
This fixes `make check' in 32 bits machines (since we are shipping 64
bits modules for testing)
Autofoo make the dist dir as readonly. If we copy it, tools needing to
create sysfs entries will not be able to do so, because they can't
create the needed directories/files.
It would be much better if autofoo allowed to let the files as is
instead of converting them to read-only.

It makes more sense to have libkmod-config.c deal with the configuration
directly and the others get the config from ctx. As a bonus point we get
a smaller binary. Following numbers are for x86-64, libkmod + kmod:
Before:
text data bss dec hex filename
128840 1496 104 130440 1fd88 tools/modprobe
After:

This loop is similar to the one that comes with install rules of
alsa-utils package. It can be easily verified by reverting commit
abd5557 and running the testsuite.
Each test must run under 2 seconds. Ideally they should run in much less
than this; just give an arbitrary number so we don't wait forever in
case we reached an infinite loop somewhere.
Keep around a stamp-rootfs file that is generated together with the
rootfs. testsuite checks each test directory if its mtime is greater
than stamp's mtime, deciding if rootfs should be re-generated.
I hate this kind of READV and WRITEV macros that Gustavo seems to love.
clang-analyzer hates them as well.
I'm not motivated enough to refactor this, but I want a clean clang
report, so just shut it up.
