# Slackware build script for nss-tls

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Notes:

# Building with --buildtype=debug makes the daemon write HTTP request
# and response headers to its stdout. This isn't very useful, so this
# script doesn't support it.

# It would be nice if the daemon would log to syslog, or had some
# runtime-configurable verbose/debug options.

# I wish git would work with this. If it would, it'd be possible
# to use 'hosts: files tls' in nsswitch.conf (curl and alpine still
# wouldn't work, but there are decent workarounds for those).

# By default, when the daemon runs as root, it switches UID/GID to
# daemon/daemon. This seems fine to me. It would be possible to
# reserve a UID/GID and build with -Duser=<blah> -Dgroup=<blah>, if
# there were any real need for it.
