# Script to manually build a Debian .deb package for snapraid on Slackware
# (using only dpkg-deb; no dpkg-buildpackage or debhelper needed)
#
# This avoids the /var/lib/dpkg/status issue entirely by:
# - Building the source directly
# - Installing into a temporary package root directory
# - Creating minimal DEBIAN/control manually
# - Packaging with dpkg-deb --root-owner-group
