Haven't we always documented uadmin(2) as the wrong way to do that? The current man page seems to be pretty clear that you're not supposed to call it unless you really know what you're doing (which would preclude calling it when the system is unstable).

At least to me, one of the basic questions is: what the heck can the administrator realistically do when the archive is out of date? It is it at all plausible that someone might fix this problem by some means that do not include just "bootadm update-archive"? If so, then what exactly is that scenario? Or is it ever possible that someone might want to continue running despite the obvious problem? Again, if so, why? If there are no realistic cases where the user can do anything but update the archive based on the current disk contents, then this looks to me like the same sort of "please hang up and dial 1" annoyance features that we ought to be avoiding. Especially so given the annoying regularity of the problem ... -- James Carlson, Solaris Networking <james.d.carlson at sun.com> Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677
