I'll note there is a second implementation that uses dell_rbu, and
that is included in each and every "Dell Update Package" (aka DUP)
BIOS update posted on support.dell.com for every Dell PowerEdge server
for the past several years.  Because the updater and they BIOS payload
are packaged in the same package, a change which would require
changing that updater will result in requiring Dell to spin and
re-release hundreds of DUPs, which would not go over well...  Thank
you for being careful not to change the interface capriciously - it
could have a huge impact on us.

Thanks,
Matt
