+Setting up a Debian SID chroot on Fedora
+-------------------------------------------
+
+Fedora does not ship `sbuild` or `schroot`, so use `debootstrap` and
+`systemd-nspawn` to create a minimal Debian SID environment for building
+packages.
+
+### Prerequisites
+
+```
+$ sudo dnf install debootstrap systemd-container debian-keyring
+```
+
+### Create the chroot
+
+```
+$ sudo debootstrap --arch=amd64 sid /srv/chroot/debian-sid http://deb.debian.org/debian
+```
+
+### Enter the chroot
+
+```
+$ sudo systemd-nspawn -D /srv/chroot/debian-sid
+```
+
+### First-time setup inside the chroot
+
+```
+# apt update && apt upgrade -y
+# apt install -y git cmake build-essential debhelper devscripts help2man \
+    libpng-dev liblcms2-dev libtiff-dev libjpeg-dev zlib1g-dev doxygen \
+    lintian libimage-exiftool-perl
+```
+
+### Bind-mount source directory and build
+
+From the Fedora host:
+
+```
+$ sudo systemd-nspawn -D /srv/chroot/debian-sid --bind=/home/aaron/src/grok:/src/grok
+# cd /src/grok
+# git archive --format=tar v20.2.5 | gzip > ../libgrokj2k_20.2.5.orig.tar.gz
+# dpkg-buildpackage -us -uc
+# lintian -EviIL +pedantic ../*.changes
+```
+
+### Re-entering the chroot later
+
+```
+$ sudo systemd-nspawn -D /srv/chroot/debian-sid --bind=/home/aaron/src/grok:/src/grok
+```
