3d7a0c5c39 build-vm, tar2fs: unify kver handling
No need to deduce kernel version again,
just save it in a temporary file.

The main reason to change what worked is
that e2k kernel-image package has Linux bits
named as image-$kver and not vmlinuz-$kver;
the guessing logic taking all of this into
account resulted in non-aesthetic patch.

NB: there's a duplicating script within
    kernel feature; it wasn't easy to avoid
    this and it might differ when handling
    multiple kernels, I didn't think much
    about this now as vm images tend to ship
    with the sole one.

39fa788ac8 build-vm: update referenced script name
It's probably a good year to get rid of this reference practice
resulting in a known sort of misdocumentation over time :-/

3f547e2504 documentation: use paths relative to toplevel dir
This change is done to reduce ambiguity in some cases;
the previous intention has been to ease navigation when
staying in a particular directory, now it's been changed
in favour of convenient toplevel `git grep' in fact.

Both variants have their pros and cons, I just find myself
leaning to this one by now hence the commit.  Feel free to
provide constructive criticism :)

Some path-related bitrot has also been fixed while at that.

d22c793ee9 initial deflogin feature (security sensitive!)
The feature officially introduces the "engineering passwords"
including empty ones which have been around since forever but
weren't properly managed (and still are not, at least until
there are no stray passwd/chpasswd/usermod calls in both the
profile, installer-features and all the other related parts).

It is based on an m-p-d init3-users script by stanv@ but was
cleaned up and restructured in a pretty severe manner; thanks
glebfm@ for additional discussion.

This also cleans up the kludge previously stuck into build-vm.

Note that vm/icewm sports graphical autologin now as well as
the default root password (which can be overridden by passing
ROOTPW=... to make but it is a change from the previous state
of affairs indeed).

67adab492f initial rootfs subprofile and services feature
This subprofile is akin to THE_* variables family: the configuration
bits and script hooks sitting there influence whatever chroot is
declared to be the user facing one in the end, whether it comes
from vm image or live subprofile.

The services feature ought to be a changeset of its own which would
be based on rootfs and become the base for ve/vm changes but I chose
to just do it atomically; some pre-existing duplicates are pruned now.

09be84beee initial vm-{net,ssh} features
A virtual machine isn't very useful if there are no means
to access it; let's bring up the basic networking and provide
root SSH access via pre-existing public key.

As the remote access with known default credentials is roughly
equivalent to just lending one's VMs to anyone with network
access to it, the fallback root password is now exterminated;
you have to provide one (or a long enough random string
if you plan to use keys only, see e.g. apg utility).

b24bd31f45 build-vm: 06syslog should differ from VE's one
There's no need to disable console as it's emulated too,
and it still can be helpful or just convenient.

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:
