devuan

We use debootstrap and need to enter the jail to fix the last stuff.

mkdir debootstrap-devuan cd debootstrap-devuan fetch http://deb.devuan.org/devuan/pool/main/d/debootstrap/debootstrap_1.0.140devuan1_all.deb tar xf debootstrap* tar xf data.tar.gz cp usr/share/debootstrap/scripts/daedalus /usr/local/share/debootstrap/scripts/

zfs create -p tank/jails/devuan debootstrap –no-check-gpg –arch=amd64 daedalus /usr/local/jails/devuan/ http://pkgmaster.devuan.org/merged/

cp /etc/resolv.conf /usr/local/jails/void/etc/resolv.conf cp /etc/localtime /usr/local/jails/void/etc/localtime

chroot /usr/local/jails/devuan /bin/bash

Set Cache-Start

echo “APT::Cache-Start 251658240;” > /etc/apt/apt.conf.d/00chroot

Fix base packages

dpkg –force-depends -i /var/cache/apt/archives/*.deb

Install OpenRC

apt –allow-insecure-repositories update apt –allow-unauthenticated install openrc

cd /usr/local/jails/devuan0/etc/ echo “root::0:0::0:0:Charlie &:/root:/bin/bash” > master.passwd pwd_mkdb -d ./ -p master.passwd

Restore the Linux passwd file

cp passwd- passwd

devuan.conf ``` exec.clean; allow.raw_sockets;

devuan {

STARTUP/LOGGING

exec.start = “/sbin/openrc default”; exec.stop = “/sbin/openrc shutdown”;

exec.consolelog = “/var/log/jailconsole${name}.log”;

test your config with

jail -c -f /etc/jail.conf.d/devuan.conf


# void
Simple! Just extract the rootfs

`zfs create -p tank/jails/void`
fetch https://repo-default.voidlinux.org/live/current/void-x86_64-ROOTFS-20250202.tar.xz
tar xf void-x86_64-ROOTFS-20250202.tar.xz -C /usr/local/jails/void/

cd /usr/local/jails/void/etc/
echo "root::0:0::0:0:Charlie &:/root:/bin/bash" > master.passwd
pwd_mkdb -d ./ -p master.passwd

cp /etc/resolv.conf /usr/local/jails/void/etc/resolv.conf
cp /etc/localtime /usr/local/jails/void/etc/localtime

now we're ready to start the jail

void.conf

exec.clean; allow.raw_sockets; #mount.devfs; # we really dont want /dev

void {

exec.start     = "/bin/sh /etc/runit/2 &";

exec.consolelog = “/var/log/jailconsole${name}.log”;

# PERMISSIONS allow.raw_sockets; exec.clean; mount.nodevfs; # empty /dev as we use devfs
