Devuan LXC container usage?

Am I the only one crazy enough to use the Devuan LXC container template in Proxmox for my home workloads?
I assume they were included in Proxmox for a reason and not just decoration.

I have used the templates for Devuan 4 and 5, and dist-upgraded a 5 template into a 6 template this week.

Re: Devuan LXC container usage?

I started to use Devuan lxc containers as well. I have prepared pct template of Devuan6 in the same way. I think much better experience in relation to LXC containers provide Incus, so recently I was thinking if would be better to start Proxmox VM and install INcus there just for LXC

Re: Devuan LXC container usage?

Basic lxc has a container template for devuan5-6 (devuan host)
(does basic minimal config like /etc/inittab config for proper shutdown and disables consoles,
but leaves all the unneeded init services intact that will error and not run proper in containers)

lxc-create --name devuan6 --template download -- --dist devuan --release excalibur --arch amd64

Use this method to create the containers till you figure out how to customize the lxc and container configs!

I prefer to roll my own (privileged lxc) by debootstrap(ing) a minbase variant and going from there
(Ignore zfs commands if you do not use it, and my paths are custom lxc locations/configs)

=============== debootstrap ===============

debootstrap --arch=amd64 --variant=minbase \
--include=ifupdown,iputils-ping,isc-dhcp-client,locales,nano,netbase,procps,whiptail \
excalibur /srv/lxc_images/devuan6 http://us.deb.devuan.org/merged

zfs snapshot m92p-sata/srv/lxc_images/devuan6@debootstrap

-------------------- basicstrap1 --------------------

lxc-attach devuan6

# Fix container shutdown
sed -i "s#^pf::powerwait.*#pf::powerwait:/sbin/poweroff#" /etc/inittab

# Disable getty (or not if you use lxc-console instead of lxc-attach)
sed -i '/tty[1-6]/s/^/#/' /etc/inittab

echo en_US.UTF-8 UTF-8 >> /etc/locale.gen
locale-gen en_US.UTF-8 UTF-8
update-locale LANG=en_US.UTF-8

echo 'US/Eastern' > /etc/timezone
ln -sf /usr/share/zoneinfo/US/Eastern /etc/localtime

zfs snapshot m92p-sata/srv/lxc_images/devuan6@basicstrap1

-------------------- basicstrap2 --------------------
#here we remove all init services that error on boot and are not functional in containers!
lxc-start -F devuan6 (should show a clean startup and a clean shutdown after these steps)

lxc-attach devuan6

cd /etc/rcS.d/
update-rc.d mountkernfs.sh disable            (/proc, /sys)

zfs snapshot m92p-sata/srv/lxc_images/devuan6@basicstrap2

-------------------- provision1 --------------------

lxc-attach devuan6

echo devuan6 > /etc/hostname

groupadd user
useradd --shell /bin/bash -m user

passwd root
passwd user

edit /etc/network/interfaces
and any other config file you need

zfs snapshot m92p-sata/srv/lxc_images/devuan6@provision1

-------------------- provision2 --------------------
apt update

apt install man vim bash-completion whiptail less
apt install rsync htop nmon ncdu ethtool psmisc tree wget

apt install dma bsd-mailx
apt install cron rsyslog logrotate

zfs snapshot m92p-sata/srv/lxc_images/devuan6@provision2

-------------------- base --------------------

check that everything works as intended
and use this as a base for all following containers
changing passwords etc... on next steps

apt install openssh-server --no-install-recommends

install opensssh-server here unless you want to reset the hosts keys
on each new container

=============== cgroups2 on devuan host (optional) ===============

update-rc.d cgroupfs-mount disable
echo 'cgroup2 /sys/fs/cgroup cgroup2 defaults,nsdelegate 0 0' >> /etc/fstab
