Solaris 11: IDRs

One of the lacking features in Solaris 11 was  the way it dealt with IDRs when performing OS update. Essentially one had to manually back out an IDR to perform an update as a separate step before an update or by adding a --reject IDRxxx (but this wouldn't necessarily be 100% correct). However, recently Oracle started publishing  IDRs in their support repo once they are integrated as an obsoleting package - long story short, it means that now one can just update OS without worrying how to back out an IDR if it has been fixed in a later release. For more details see here.
