[bcc'ed to committers, hackers]
My last pamphlet was sufficiently well received that I was not
scared away from sending another one, and today I have the time
and inclination to do so.
I've had a little trouble with deciding on the right distribution
of this kind of stuff, this time it is bcc'
uot; basis.
I actually think we should not get into the jail thing, but rather
make them inheritable like other credentials, so the structure
containing the stuff should hang of the proc structure, and hey
wait, we already have this "struct ucred" hanging there.

So far IPv6 has gotten no futher than OSI ever did.

I'm not against adding IPv6 functionality to jail(2), my point is
merely that until somebody who has sufficient time & ability to
fiddle with it does it, it's not going to happen.
The usual rule applies:

Yes, that also matters, this is a administrative facility.

FreeBSD -- It will take a
similar. Only
very recently used inodes are in memory actually. They die with the vnode
which maybe still die to fast.
Putting the inode with the data saves a little less than one diskaccess
on average per file, which for truly random access filesystems is a good
thing.

Not really. The intent of the driver is to interface to ascii

No, in fact the AIX version was so hard to port that OSF eventually
had to give up trying. It was rather closely married to the VM
