DH_USRLOCAL(1) Debhelper DH_USRLOCAL(1)
dh_usrlocal - migrate usr/local directories to maintainer scripts
dh_usrlocal [debhelperoptions] [-n]
dh_usrlocal is a debhelper program that can be used for building
packages that will provide a subdirectory in /usr/local when installed.
It finds subdirectories of usr/local in the package build directory,
and removes them, replacing them with maintainer script snippets
(unless -n is used) to create the directories at install time, and
remove them when the package is removed, in a manner compliant with
Debian policy. These snippets are inserted into the maintainer scripts
by dh_installdeb. See dh_installdeb(1) for an explanation of debhelper
maintainer script snippets.
When the DEB_RULES_REQUIRES_ROOT environment variable is not
(effectively) binary-targets, the directories in /usr/local will be
handled as if they were owned by root:root (see below).
When the DEB_RULES_REQUIRES_ROOT environment variable has an effective
value of binary-targets, the owners, groups and permissions will be
preserved with the sole exception where the directory is owned by
If a directory is owned by root:root, then ownership will be determined
at install time. The ownership and permission bits will either be
root:root mode 0755 or root:staff mode 02775. The actual choice
depends on whether the system has /etc/staff-group-for-usr-local (as
documented in the Debian Policy Manual <section>9.1.2 since version
Do not modify postinst/prerm scripts.
Note that this command is not idempotent. dh_prep(1) should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
