# Proposal: how should we deal with Linux binary packages packages
#
# Currently supports:
#   * rpm
#   * "plain" -> .tgz, .tbz2,
#   * slackware packages (.tgz, but need slackware_compat)
#
# TODO:
#   * deb
#
# I have included comments, indents and unneeded spacings, so you can
# read this file more easily.

# LINUX_BASE_PREFERRED should be set in mk/defaults or /etc/mk.conf
# This setting show us the user / sysadmin preference for a given linux base
#

LINUX_BASE_PREFERRED?=		suse

#
# LINUX_BASE_REQUIRED is *per package* setting (SuSE-only apps set this to
# suse, Slackware apps - to slackware and so on)

#
# TODO: make it possible, that we somehow can override LINUX_BASE_VERSION
# and make a given package require at least x.x.x version of linux_base
