Update IPMI/iDRAC firmware on Dell from Debian Linux

1. This is inspired by http://jinntech.blogspot.be/2010/04/upgrading-idrac-firmware-dell-ipmi.html slightly reworked to make it work on Wheezy... Thanks to the original author for his work.
2. install dependencies:#aptitude install ia32-libs rpm
3. Change /bin/sh to be bash, since this is what the script expect (my take, if you want bash, just #!/bin/bash)# ln -s /bin/bash /bin/sh 
4. extract the archive:#bash ESM_Firmware_CMDN0_LN32_1.95_A00.BIN --extract .
5. A bit of hackery to get sub tools to work ...#export LD_LIBRARY_PATH=/root/ipmi_upgrade/hapi/opt/dell/dup/lib/
   and assuming the archive was extracted in /root/ipmi_upgrade ...
6. Run the actual update tool:./bmcfwul -i=payload/firmimg.d6
   which should give something along the lines of:

   iDRAC6 Firmware Upgrade Utility Version:  1.4.02.119

   Please wait... -instsvcdrv: unrecognized service
   Firmware Version                                  Current      Image

                               Bootloader version    1.13.7       1.13.7      

and voilà... ipmi is upgraded :-)
