	Здравствуйте.
За прошлую неделю особых изменений не было -- всё так же висит ряд
экспериментальных коммитов и бранчей, не созревших для публикации.
Идёт доработка altlinux-p7-server.iso.

Среди прочего сейчас выясняю текущее состояние /vm/orthodox --
пока при попытке использовать приложенный хук для формирования
vm-profile.scm вместе с

# FIXME: /vm behaviour should be controllable in some sane manner
%post stage2
sed -i 's,^\(X-Alterator-URI=\).*$,\1/vm/ortodox,' \
        %_datadir/install2/steps/vm.desktop

в installer-distro-altlinux-server.spec (этот субпакет
Requires: alterator-vm) приводит к вот такой картинке:

(обратите внимание на "0 МБ свободно" и "требуется 0 МБ").
