# preinst script for salt-common.
#
# See: dh_installdeb(1).

set -e

# Summary of how this script can be called:
#        * <new-preinst> 'install'
#        * <new-preinst> 'install' <old-version>
#        * <new-preinst> 'upgrade' <old-version>
#        * <old-preinst> 'abort-upgrade' <new-version>
# for details, see https://www.debian.org/doc/debian-policy/ or
# the debian-policy package.

# Source setup configuration if present. The DEB-conventional location is
# /etc/default/salt-setup; /etc/sysconfig/salt-minion-setup is honored as
# well for cross-distro parity with the RPM packaging. Either file may
# pre-set SALT_HOME, SALT_USER, SALT_GROUP, SALT_NAME, SALT_SHELL, or
# SALT_EXTRAS_DIR. Values in the sourced files win over inherited env
# vars; the [ -n ... ] || guards below preserve whatever was set,
# falling back to the hardcoded defaults only when nothing was supplied.
