Do you really believe that Sun will help such a customer?
There are many bugs in Solaris (I remember e.g. some showstopper
bugs in the multimedia area) that are not fixed although they are known
since a very long time (more than a year).
There is a bug in ACL handling in Sun's tar (reported by me in 2004 or even
before) that is not fixed. As a result in many cases ACLs are not restored.
Note that bugs in star are fixed much faster and looking back at the 28 years
of history with star, I know of not a single bug that took more than 3 months
to get a fix. Typically, bugs are fixed withing less than a week - many bugs
even within a few hours. This is a support quality that Sun does not offer.
So please explain us where you see a problem with star......
