#
# Simple script to generate a deb package for a Linux kernel. All the
# complexity of what to do with a kernel after it is installed or removed
# is left to other scripts and packages. Scripts can be placed into the
# preinst, postinst, prerm and postrm directories in /etc/kernel or
# /usr/share/kernel. A different list of search directories can be given
# via KDEB_HOOKDIR. Scripts in directories earlier in the list will
# override scripts of the same name in later directories. The script will
# be called on package installation and removal.
