pacstrap inside package()

I have this makefile which installs a new systemd-nspawn container:

MACHINES_DIR=/var/lib/machines
CONT_NAME=generic-arch

all:
        echo "nothing to build, just 'make install'"

install:
        mkdir -p $(DESTDIR)$(MACHINES_DIR)/$(CONT_NAME)
        pacstrap -K -c $(DESTDIR)$(MACHINES_DIR)/$(CONT_NAME) base
        install -D -m644 generic-arch.nspawn $(DESTDIR)/etc/systemd/nspawn/$(CONT_NAME).nspawn
        cat init.sh | systemd-nspawn -P -D $(DESTDIR)$(MACHINES_DIR)/$(CONT_NAME)

init.sh:

#! /bin/bash

LC_ALL=C tr -dc '[:graph:]' </dev/urandom | head -c 16 | passwd -s
systemctl enable systemd-networkd
systemctl enable systemd-resolved

generic-arch.nspawn:

[Exec]
PrivateUsers=managed
ResolvConf=bind-static

[Network]
Bridge=br0

I created a PKGBUILD for that setup:

pkgname="msl-base-arch"
pkgver=r3.a235591
pkgrel=1
pkgdesc="Base arch container"
arch=(any)
url=""
license=('unknown')
groups=()
depends=('systemd' 'bash')
makedepends=('git' 'arch-install-scripts' 'pacman' 'fakeroot' 'systemd')
provides=("${pkgname}")
conflicts=("${pkgname}")
replaces=()
backup=()
options=()
install=
source=("${srcdir}/${pkgname}::git://generic-arch/msl-gen-cont.git")
noextract=()
sha256sums=('SKIP')

pkgver() {
        cd "${srcdir}/${pkgname}"
        printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
}

prepare() {
        cd "${srcdir}/${pkgname}"
        rename generic-arch base-arch *
        sed -i 's/generic-arch/base-arch/g' *
        sed -i 's/br0/msl-util-br/g' *
}

package() {
        cd "${srcdir}/${pkgname}"
        make DESTDIR="$pkgdir" install
}

When I run makepkg, I get the following:

==> Making package: msl-base-arch r2.0eddcf5-1 (Mon Apr 13 22:25:34 2026)

    Aborting...

I get the same error when running

makechrootpkg -c -x failure -r $CHROOT

When I add sudo before pacstrap, makepkg prompts me my own password and fails at the fourth line of make install, while makechrootpkg prompts for builduser's password.

Why does pacstrap require root privileges in fakeroot? What am I missing here?

Re: pacstrap inside package()

Does "pacstrap -N -…" work?
