[Lxc-users] Problem with: lxc.autodev=1

[Andreas Otto]

Hi,

as one solution I try to switch my lxc container on opensuse 12.3 back 
to sysvinit-init
but this seems not to work eigther...

  # zypper --root /var/lib/lxc/nhi2/rootfs in sysvinit-init

Problem: systemd-sysvinit-195-13.18.1.x86_64 steht in Konflikt mit 
namespace:otherproviders(sbin_init), angeboten von 
sysvinit-init-2.88+-83.2.1.x86_64
Lösung 1: Folgende Aktionen werden ausgeführt:
   Deinstallation von systemd-sysvinit-195-13.18.1.x86_64
   Deinstallation von aaa_base-12.3-14.8.1.x86_64
   Deinstallation von patterns-openSUSE-base-12.3-7.10.1.x86_64
   Deinstallation von netcfg-11.5-14.1.1.noarch
   Deinstallation von ghostscript-fonts-std-9.06-2.1.1.noarch
   Deinstallation von ghostscript-fonts-other-9.06-2.1.1.noarch
   Deinstallation von ghostscript-9.06-4.1.1.x86_64
   Deinstallation von ghostscript-x11-9.06-4.1.1.x86_64
Lösung 2: sysvinit-init-2.88+-83.2.1.x86_64 nicht installieren

Wählen Sie aus den obigen Lösungen mittels Nummer oder brechen Sie a(b). 
[1/2/b] (b):


=> I think it os not an good solution to delete aaa_base .-(

as second solution I try to don't use autodev=1 and to create the 
devices by hand ...

but "hand-made" devices together with systemd ...

the system immideadly crash -> it seems somthig "eat" alle the memory :-(
