 If 'command' is unspecified, ${0##*/} will launch /bin/bash.
 
+Note that when using arch-chroot, the target chroot directory *should* be a
+mountpoint. This ensures that tools such as pacman(8) or findmnt(8) have an
+accurate hierarchy of the mounted filesystems within the chroot.
+
+If your chroot target is not a mountpoint, you can bind mount the directory on
+itself to make it a mountpoint, i.e. 'mount --bind /your/chroot /your/chroot'.
