You need to emulate zones/containers with chroot.

I put my chroot scripts here:
https://drive.google.com/drive/folders/1lUKFdbW9APwyy04zoRTUKYcxZj-6rLFw

If you create /opt/netbsd_chroot/scripts and copy them there. You need
to customize chroot.sh as I usually have src, xsrc, pkgsrc and distfiles
under /opt.

# ls -1 /opt/netbsd_chroot/scripts/
chroot.sh
mk.pkgsrc.conf
pkgbuild

When I run chroot.sh it automatically sets up all mount points and runs
chroot:

# /opt/netbsd_chroot/scripts/chroot.sh
