If you run dmidecode|grep UUID you are given a "globally unique string of characters" which can be used for licensing purposes. In linux, the format is usually something like this: 44454C4C-3200-1047-8047-A4D04F394F30
In solaris, the format is usually something like this: 0ab290a98
So, what is this number actually based on? Originally I thought it would be based on drive or volume serial number, but that would be odd given the differing formats (though one is zfs, the other is extN). Any ideas would be appreciated.
