mountvirtfs-early and mountvirtfs

I am working on a port of the Linux Kernel to the ARM architecture and have created a Ramdisk which I am using to boot Linux. Everything is working fine, and I am able to boot and work on it without a problem. However, during the boot process, I get these two warnings/errors:

Code:

/etc/rc.d/rcS.d/S03mountvirtfs-early: /etc/rc.d/rcS.d/S03mountvirtfs-early: 151: readlink: not found
0
/etc/rc.d/rcS.d/S09mountvirtfs: /etc/rc.d/rcS.d/S09mountvirtfs: 151: readlink: not found

In both these scripts, line 151 is:

Code:

MTAB_PATH="'readlink /etc/mtab || :'"

The command readline is provided by Busybox.

Code:

# busybox 
BusyBox v1.2.2 (2007.03.11-00:56+0000) multi-call binary

Usage: busybox [function] [arguments]...
   or: [function] [arguments]...

        BusyBox is a multi-call binary that combines many common Unix
        utilities into a single executable.  Most people will create a
        link to busybox for each function they wish to use and BusyBox
        will act like whatever it was invoked as!

Can anyone tell me what might be going wrong.

P.S. Apologies for cross posting, I have asked the same question on Gentoo Forums as well.

readlink needed to be called with the full path, i.e., /usr/bin/readlink. Changed the scripts. Solved.
