  /sbin/MAKEDEV: don't know how to make device "tty0"
  dpkg: error processing package makedev (--configure):
   subprocess installed post-installation script returned error exit status 1
  Errors were encountered while processing:
   makedev
  E: Sub-process /usr/bin/dpkg returned an error code (1)

  The workaround is similar to 1675163 except in this case the post-
  installation script should check for "container=zone" in
  '/proc/1/environ':

  
  if grep -q container=zone /proc/1/environ
  then
      echo "lx-brand container detected."
      exit 0
