+/* Run mke2fs to create a filesystem of type fstype, where fstype
+ * is the string "ext2", "ext3" or "ext4".
+ *
+ * This is more complex than it seems.
+ *
+ * On RHEL 5, the -t option was deprecated. Moreover RHEL <= 5.4
+ * systems have a bug where the -t option doesn't work (it doesn't
+ * correctly ignore the following argument).
+ *
+ * On RHEL 5, to create an ext4dev filesystem you have to use
+ * the special command /sbin/mke4fs. This can also create ext2/3
+ * using the '-t fstype' option.
+ *
+ * On Fedora 11+, mke4fs was renamed mke2fs, and it can use the
+ * '-t fstype' option to specify the filesystem type.
+ *
+ * So it seems best to run /sbin/mke4fs if it exists, or /sbin/mke2fs
+ * otherwise. We specify e4fsprogs in the package list to ensure it
+ * is loaded if it exists.
