# This script can be installed to the same directory where the script
# that starts plymouth is installed, because it will start after it. It
# is, however, much better for performance to install in the directory
# that contains the first scripts to be started, usually 'init-top'.
# Installation options:
#
#   1. As a distro/vendor script, put it in directory:
#     (a) '/usr/share/initramfs-tools/scripts/init-top' -- faster boot;
#
#     (b) '/usr/share/initramfs-tools/scripts/init-premount' -- slower boot;
#
#   2. As an admin script, put it in directory:
#     (a) '/etc/initramfs-tools/scripts/init-top' -- faster boot;
#
#     (b) '/etc/initramfs-tools/scripts/init-premount' -- slower boot;
