Package: lxc-templates
Version: 3.0.4-5
Severity: normal
X-Debbugs-Cc: eric.gerbier at free.fr

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   I am trying to create an alpine lxc container

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     lxc-create -t alpine -n alpine

   * What was the outcome of this action?
   mknod: dev/zero: Le fichier existe
lxc-create: alpine: lxccontainer.c: create_run_template: 1616 Failed to create container from template
lxc-create: alpine: tools/lxc_create.c: main: 319 Failed to create container alpine

   * What outcome did you expect instead?
   the lxc container should be created with the following message
   ==> Container's rootfs and config have been created


   devices seems to be already created
   The problem can be fixed with the following patch
