+# On a server with tiny 4G partitions for /usr, /var, /tmp, /opt,
+# etc., no partition had room for a chroot. Using RAM:
+#   mount -t tmpfs -o size=10G tmpfs /srv
+# was sufficient for a proof of concept, but for real work it's
+# necessary to obtain sufficient storage, e.g.:
+#   parted --align optimal /dev/sdb -- mklabel msdos mkpart primary ext4 1MiB
