+# Usually you want to use a partition.
+# If you specify a string *without* /dev/ in the beginning, grml-debootstrap
+# assumes you want to install Debian into a directory. MKFS, TUNE2FS, GRUB and
+# FSCK will be ignored.
+# Make sure the TARGET-directory points to a filesystem which has the dev, exec
+# options enabled.
+# Default: no default.

+# TARGET='/dev/sda1' # install to partition /dev/sda1
