One of my FreeBSD boxes is a 7-STABLE/amd64 one on ZFS, now in
production for over a 1.5 years now and which receives regular upgrades.
The last installation of FreeBSD 7-STABLE was just about 2 weeks ago.
Today the upgrade failed the first time:

Fortunately, I was able to quickly recover via "/rescue/cp" by copying
a libc.so.7 from a Jail to the host system (where the upgrade was
performed). But why has this problem occurred now.
Well, /lib is on ZFS and I can remember from the past that ZFS did not
honor chflags. But remains two questions:
1. I thought chflags support for ZFS was added already in the past.
Can it be that just a _few_ chflags flags are supported? It looks
like uchg works while the above schg fails.
2. Assuming that schg was never supported on ZFS by us, why did the
upgrades in the past on this FreeBSD 7-STABLE box never failed until
now? Why now the first time? I would have expected that it already
failed from day zero with the above error.
As workaround I've now put a NO_SCHG=yes into /etc/make.conf and
performed the upgrade from scratch. Now it succeeded, of course. But I
still do not know the answer to the above two questions and this makes
me still feel a little bit unsure about the whole situation...
PS: At a mergemaster run I now got a problems which looks related:
mv: /var/db/mergemaster.mtree: set flags (was: 00000000): Invalid argument
Yes, /var is also on ZFS here. Same problem as it looks. But I'm
sure also this error did not occur in the past...
