The problem is that you need to initialize an Rx connection,
authenticate, do the necessary directory lookups (including volume
lookups when you hit mountpoints), and then do the setattr request.
While we could steal code from the cache manager, I don't think it's
very feasible.
Are you willing to accept as part of the answer a kernel module which
defines a new system call which is like chown() but without the uid
check? This means adding a file under /kernel, modifying
/etc/name_to_sysnum, and of course having a local problem which
invokes the system call.
Of course, then you have all the hair of implementing a loadable
Solaris kernel module, but at least that's documented.
