# Usage: rpi-clone-setup {-t|--test} hostname
|
|
# eg: sudo rpi-clone-setup bozo
|
|
#
|
|
# This script is automatically run by rpi-clone (when it is given -s options)
|
|
# to setup an alternate hostname. A cloned file system mounted on /mnt/clone
|
|
# is expected unless testing with the -t option.
|
|
#
|
|
# Or, this script can be run by hand at the end of a clone when rpi-clone
|
|
# pauses with the cloned file systems still mounted on /mnt/clone.
|
|
#
|
|
# Or, run this script by hand with -t to process files in test directories
|
|
# under /tmp/clone-test. Run -t and look at the files to see if the files
|
|
# have been edited OK.
|
|
# eg: sudo rpi-clone-setup -t bozo
|
|
#
|
|
# This is a starter script that handles only /etc/hosts and /etc/hostname.
|
|
# Make sure the script works correctly for your /etc/hosts file.
|
|
#
|
|
# If adding a customization for another file:
|
|
# Add the file to file_list.
|
|
# If needed, add a mkdir -p line to the "if ((testing))" part.
|
|
# Add the scripting necessary to customize the file.
|
|
# Test new scripting by running: rpi-clone-setup -t newhostname
