[SOLVED] File lxc-slackware in package lxc needs updated

Try to set up an lxc container in -current following the guide:

https://docs.slackware.com/howtos:misc:lxc

And it fails:

Code:$ cat /etc/lxc/slackware.conf
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = lxcbr0Code:# MIRROR=https://mirrors.slackware.com/slackware/ lxc-create -n SlackwareSBo -t slackware -f /etc/lxc/slackware.conf
installpkg is /sbin/installpkg
slackpkg is /usr/sbin/slackpkg

Your slackpkg.conf is outdated. Please, edit it using slackpkg.conf.new
as example or overwrite it with slackpkg.conf.new.

You can use 'slackpkg new-config' to do that.

Error creating container SlackwareSBoI discovered it's because of an outdated slackpkg.conf embedded in /usr/share/lxc/templates/lxc-slackware. Here is the diff I applied:

PACKAGE DESCRIPTION:
# xz (compression utility based on the LZMA algorithm)
#
# LZMA is a general purpose compression algorithm designed by Igor
# Pavlov as part of 7-Zip. It provides high compression ratio while
# keeping the decompression speed fast. XZ Utils are an attempt to make
# LZMA compression easy to use on free (as in freedom) operating
# systems.
#
# The people most responsible for xz are Igor Pavlov, Ville Koskinen,
# and Lasse Collin. Homepage: http://tukaani.org/xz/

Configuring...

Adding an etc/fstab that must be modified later with the
full path of the container's rootfs if you decide to move it.

Error creating container SlackwareSBoI wonder with the addition of PAM, do more packages need to be added to minimal-lxc.template (also defined in lxc-slackware)?

P. S. On 14.2 I build SBo packages using chroot with my own homegrown scripts using overlayfs to always have a clean build system. I thought I'd take the opportunity to investigate using lxc instead - this is the first time I've played with lxc. So if I'm doing something wrong let me know! Also I don't use slackpkg (well, I guess I am now with lxc) so my patch needs to be checked by those who actually know what they're doing.
