	# Various packages dynamically add users and groups to the system at package
	# install time. For programs that do not care what the uid/gid is of the
	# resulting users/groups, the order of the install will determine the final
	# uid/gid. This can lead to non-deterministic uid/gid values from one build
	# to another. Use the following settings to specify that all user/group adds
	# should be created based on a static passwd/group file.
	#
	# Note, if you enable or disable the useradd-staticids in a configured system,
	# the TMPDIR may contain incorrect uid/gid values. Clearing the TMPDIR

	# IPK Hierarchical feed
	#
	# In some cases it may be desirable not to have all package files in the same
	# directory. An example would be when package feeds are to be uploaded to a
	# shared webhosting service or transferred to a Windows machine which may have
	# problems with directories containing multiple thousands of files.
	#
	# If the IPK_HIERARCHICAL_FEED variable is set to "1", packages will be split
	# between subdirectories in a similar way to how Debian package feeds are
	# organised. In the hierarchical feed, package files are written to
	# <outdir>/<arch>/<pkg_prefix>/<pkg_subdir>, where pkg_prefix is the first
	# letter of the package file name for non-lib packages or "lib" plus the 4th
	# letter of the package file name for lib packages (eg, 'l' for less, 'libc' for
	# libc6). pkg_subdir is the root of the package file name, discarding the
	# version and architecture parts and the common suffixes '-dbg', '-dev', '-doc',
	# '-staticdev', '-locale' and '-locale-*' which are listed in
	# meta/conf/bitbake.conf.
	#
	# If IPK_HIERARCHICAL_FEED is unset or set to any other value, the traditional
	# feed layout is used where package files are placed in <outdir>/<arch>/.
