This must be done to ensure that its dependencies are not removed
after uninstalling the interactivesystem package. Relevant only
for systems installed from packages. Not relevant for live and
rootfs, since all packages will be marked as manually installed.

ldv@ has dropped sysklogd from sisyphus due to
its long-standing FTBFS and "other problems":
http://git.altlinux.org/tasks/archive/done/_207/211999/logs/events.6.1.log

The current recommended replacement is rsyslog
which is fine by itself but really overcomplicated
for the barebones logging system we usually need...

This is to avoid systemd components getting pulled in
during early dependency resolution stage for no good
reason (see also http://bugzilla.altlinux.org/30806);
should be fixed within mkimage so that hardwiring
both sysklogd and etcnet here gets unneccessary.

This reverts commit 1c44272f
which breaks p7 builds with sysvinit emitting this message:

  E: Couldn't find package systemd-services-

It's the very same problem that must be solved within mkimage:
some package lists get expanded early and some late thus having
no chance to influence apt's choices of alternatives made early
(in fact, too early).

Until that, here's another kludge...

PS: turns out that ^systemd- is not "drop ^systemd" but rather:
    systemd-analyze
    systemd-coredump
    systemd-journal-gateway
    systemd-networkd
    systemd-sysvinit
    -- thus one /really/ wants something else.

The problem with initial implementation (commit 62e7e9c1)
is that there's no systemd-services package in p7/branch
thus apt complains about an attempt to remove something
that doesn't even exist in the first place.

The issue at hand is that interactivesystem pulls in
network-config-subsystem and that one has several providers
by now, systemd-networkd being one of them since recently
(and pulling in systemd).

Just the same problem as with systemd-journal; both might be
fixed by reworking mkimage to allow for different package name
resolution modes:

- "slap everything together and resolve with one-shot"
  to handle conflictless situations (most of those);
- "process multiple transactions to allow for conflicts"
  thus making it possible to include e.g. a few MTAs into
  the provided package base.

Ensure that systemd is outside by explicitly telling so
in the pkglist.

This one is finally there and should help reduce the
systemd-induced mess in package lists and specifications.

- drop hardwired kernel flavour from pkglists
- today's std-ng lacks aufs, let's switch to un-def
- second assault at KERNEL_PACKAGES_REGEXP
- re-introduced kpackages (builds ok)

PS: base lists: switch to grub, add udev, cleanup

- syslinux: menu.c32 works
- features: initial draft
  + memtest
- mv pkg/ pkg.in/
  + server-base: include openssh-blacklist by default
- mv isodata/ copy/
- README: changed to utf8, added an URL

- s/stage2/install2/g
- added pkg/lists
- initial README (ru_RU.KOI8-R)
- mkimage topdir is in image.in/, really (off-tree build)
  + initial bin/mktmpdir
  + BUILDDIR (works)
- s/cd/iso/
- drop --with-distro (considered harmful)
