If you want to be well armed for that debate, study this comparison of the commands and capabilities of each OS before the spittle starts flying:
For instance, did you know that the command to configure your wireless network in Solaris 11 is not
ipadm for manual configuration, and
netcfg for automatic configuration? Personally, I think the change was made to correct the grievous offense of spelling out "
config" in the
wificonfig command, instead of sticking to the widely accepted "
cfg" convention, but loathe as I am to admit it, there may have been additional reasons for the change.
This doc was written by the Solaris Documentation Team, and it not only compares the major features and command sequences in Solaris 11 to those in Solaris 10, but it links you to the sections of the documentation that explain them in detail.
