cb764516eb build-vm: standalone build is a must, too
The problem was spotted by Alexander Bandura:
bin/tar2vm wasn't present in the generated profile.

I considered extending features.in/Makefile to include
bin/ alongside lib/ but that would make the helper's location
unpredictable (unless BUILDDIR is specified explicitly) so
restricting sudoers would be harder; worse yet, the copied file
would come with write access for the user building an image.

The implications in restricted case are complex enough anyways
so the recommended implementation would only include a fixed
readonly location like /usr/share/mkimage-profiles/bin/tar2vm
as laid out in doc/vm.txt, and that means it's in the metaprofile
not a generated profile.

75f7c62bd1 initial build-vm feature
Yes, mkimage-profiles is now able to build VM disk images.
So far the support is pretty basic:

- a single hard drive image with a single partition/FS
- only stock root password is configurable
- LILO is hardwired as a bootloader

The resulting images tend to boot under qemu/kvm though.

Please see doc/vm.txt for the warning regarding additional
privileges and setup required.  This was started back in
February but I still hoped to avoid sudo/privileged helper
(and libguestfs is almost as undistributable as can be)...

Thanks:

665c70a444 use PATH instead of hardwired pathlets
bin/ prefix tried to become a permatemp(tm).  No way.

5dba27d011 main.mk: factored out help targets
These are better off in their own lib/help.mk

9304c12c58 fix toplevel arch/distro loops
There was a somewhat subtle Makefile->main.mk rename leftover
lurking in "everything" target: the default Makefile got used,
not the supposed main.mk -- which resulted in an attempt to
get way too much job done (the number of builds per target
became $ARCH squared, not just $ARCH).

Huge thanks to led@ for being an inspiring pedantic!

2f307ffffb main.mk introduced, lib/*.mk partially rewritten
The former toplevel Makefile is now toplevel main.mk;
this change allows for multi-target, multi-arch processing
in the current toplevel Makefile.

As the "build" symlink semantics change quite considerably
when one is doing bulk builds (several pruned builddirs might
be useful for comparison), BUILDDIR is now much more likely
to be recreated: the cases when it will persist are when it's
either a single-image build or when the prefix hasn't changed.

There are some more or less subtle bugfixes and enhancements
all over the map as well.

Done within 20111230..20120102 timeframe, actually...
