I don't _think_ that can happen with the .dep files since they're
machine-generated, but the config files can and do contain empty lines
to aid readability.
(Not found on Android, so I haven't tested this, but the code already
even contained a special case for empty lines. I haven't touched the
/proc/modules loop because the kernel definitely isn't going to insert
empty lines, and that code _would_ need to be modified to cope with
empty lines, and since I can't test this, that would be not just
pointless but also irresponsible!)

I need to set up a test environment for this...

I accidentally added a tab in xargs.c, so as penance I'll clean up all
the tabs.
|
|
Without this change, a successful modprobe on Android exits with status 1
because Android doesn't have /etc/modprobe.conf or /etc/modprobe.d/ ---
neither of which seem to be required on desktop Linux either.
|
|
Otherwise in verbose mode we output bogus errors instead of `Success`.

modprobe was failing if you `modprobe a.ko`, then `modprobe b.ko` where b.ko
depends on a.ko --- b.ko will fail to load because a.ko is already loaded.
The code to handle this was incorrectly checking `rc` rather than `errno`
against EEXIST.
(We should pull the insmod.c equivalent of `ins_mod` out into lib/
and reuse it in modprobe.c, but I didn't want to get bogged down.)

The finit_module() system call, introduced in Linux 3.8, reads the
module from a supplied file descriptor. This allows the kernel to do
security checks based on the file's location.

While most systems have their kernel modules, modules.dep etc located at
/lib/modules/`uname -r` this is not always the case.
The -d option may be used to specify a nonstandard path for these files.
It may be used more than once to specify multiple directories where
these files may be found.

sizeof(int) != sizeof(size_t) for LP64, leading to hilarity^Wcrashes.
|
|
add xopenro() that takes one argument and understands "-" means stdin,
and switch over lots of users.

both did it) so use getbasename instead.

Given modprobe -a, it's important to not exit early for a failure to
load a module; additionally, the rest of the code presumes that this
can fail without exiting.

portability.h.patch - it is for O_CLOEXEC, as compiler complained of it.
Makefile.patch - for cleaning generated/*.o files and libopts.dat file
[Fixup to uniq.c from Rob.]

some whitespace and bracket cleanups.
|

Move <fnmatch.h> to toys.h, since it's POSIX.
Avoid duplicating code in an if/else block.
Terser error messages, spelling.
Don't always print the state.
