#
# Instructions:
#
# 1. Place your files into system folder (delete the placeholder file)
# 2. Fill in your module's info into module.prop
# 3. Configure the settings in this file (config.sh)
# 4. If you need boot scripts, add them into common/post-fs-data.sh or common/service.sh
# 5. Add your additional or modified system properties into common/system.prop

# Permissions

  # set_perm  <filename>                         <owner> <group> <permission> <contexts> (default: u:object_r:system_file:s0)
  # set_perm  $MODPATH/system/bin/app_process32   0       2000    0755         u:object_r:zygote_exec:s0

  # set_perm  $MODPATH/system/lib/libart.so       0       0       0644

  # The following is default permissions, DO NOT remove
  set_perm_recursive  $MODPATH  0  0  0755  0644
  
  # Permissions for the props file
  set_perm $MODPATH/system/$BIN/props 0 0 0777

# update-binary. Refrain from adding code directly into update-binary, as it will make it
# difficult for you to migrate your modules to newer template versions.
# Make update-binary as clean as possible, try to only do function calls in it.
