There are no jails on that host.

In fact, there is pretty much nothing on that host (8.4-RELEASE-p7
i386), it is just a slave nameserver for a dozen zones running named
from the base system.

But even if someone had a crazy idea to run freebsd-update inside a
jail (unstead of using the -b option), each process would happily have
its own copy of jailed workdir, instead of fighting for the main workdir like
this:

rm: filelist: No such file or directory
cut: INDEX-PRESENT.tmp: No such file or directory
join: INDEX-PRESENT.tmp: No such file or directory
rm: INDEX-PRESENT.tmp: No such file or directory
grep: INDEX-OLD: No such file or directory
grep: INDEX-OLD: No such file or directory
grep: INDEX-OLD: No such file or directory
grep: INDEX-OLD: No such file or directory
grep: INDEX-OLD: No such file or directory
comm: INDEX-OLD: No such file or directory
sort: open failed: INDEX-OLD: No such file or directory
