And if you remove the extension .sh, then it is also backwards
compatible with Debian 4.0 "Etch" :)
# Define your network setup for the InitRAMFS via IP variable
#
# Still a kernel ip parameter will override any InitRAMFS config
# setting (see script /usr/share/initramfs-tools/init).
#
# Additional information:
# * https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt
# In Debian as kernel command via /etc/default/grub
# * The "variable" ${hostname} (case-sensitive) will be replaced on InitRAMFS
creation
# with the current host name through the hook `set_hostname_in_network_config`
# This allows the machine to be registered with its name in DNS.
IP=::::${hostname}
#!/bin/sh
#
# This InitRAMFS hook provides:
# Simple script to set IP parameter in InitRAMFS config with current
# hostname, instead of manually maintaining InitRAMFS config.
