+Check if symlinks are valid
+
+When using root option and $initd/$bn is a symlink, the script would fail because
+the symlink points to a path on target. For example:
+
+/path/to/target/rootfs/etc/init.d/syslog -> /etc/init.d/syslog.busybox
+
+Hence, [ -f /path/to/target/rootfs/etc/init.d/syslog ] condition would return
+false.
+
+This patch adds the posibility to check whether the file the symlink points to
+actually exists in rootfs path and then continue.
