# 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

}

```

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.nodevfs; # empty /dev as we use devfs
