I'd suggest using a less general term ("pkg-lock", maybe?) and
consider using zonecfg instead.
So what happens with the default sparse-root zones? If I have a zone
locked and I try to remove a package from the global zone, what
happens? The bits are going to disappear from the non-global zone
(because it's just using lofs mounts), but the packaging data won't be
removed. It'll be a phantom. Similarly, adding packages becomes a
bit strange. Is this feature available only with whole-root zones?
What happens when the lock is disabled? If I add another package to
the global zone that depends on things that were added while the lock
was enabled, does that work? Do I get a flood of things hauled into
the now-unlocked non-global zone by dependency, or does the pkgadd
just fail? The system is in a funny state at this point.
What happens when a package has system-wide effects? For example, if
I remove a package containing a device driver from the global zone,
there's no way that package can still exist in any non-global zone, is
there? It doesn't matter whether that lock flag is set -- because
kernel modules exist only in the global zone, if that package is
removed, the non-global zone (even a whole-root zone) will have to
lose the device.
Otherwise, it looks like a fairly reasonable RFE to me, though I'd be
a bit worried about the long-term administrative effects. What
distinguishes a pkgadd done for the purpose of adding new application
software from a pkgadd done for the purpose of maintaining the system
itself seems like a bit of a grey area. (You mention patches, but
patches likely aren't the only issue here.)
Are you looking for someone to file the RFE, or are you planning to
visit bugs.opensolaris.org?
