# postinst script for cpufreqd
4
# see: dh_installdeb(1)
8
# summary of how this script can be called:
9
# * <postinst> `configure' <most-recently-configured-version>
10
# * <old-postinst> `abort-upgrade' <new version>
11
# * <conflictor's-postinst> `abort-remove' `in-favour' <package>
13
# * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
14
# <failed-install-package> <version> `removing'
15
# <conflicting-package> <version>
16
# for details, see http://www.debian.org/doc/debian-policy/ or
17
# the debian-policy package
19
# quoting from the policy:
20
# Any necessary prompting should almost always be confined to the
21
# post-installation script, and should be protected with a conditional
22
# so that unnecessary prompting doesn't happen if a package's
23
# installation fails and the `postinst' is called with `abort-upgrade',
24
# `abort-remove' or `abort-deconfigure'.
26
# Source debconf library.
