Maybe they want the timezone to be correct if you boot into
single user mode and don't mount /usr?
*shrug*-- maybe, but if you don't mount /usr, the system isn't
capable of running much which cares about the timezone. Even syslogd
itself is under /usr/sbin

I think the ln-s line is backwards, I didn't check it. I think it's
been a while since they used softlinks for localtime
The use of "ln -s" will work just fine as written. I don't know why
tzsetup makes a copy of the zoneinfo file rather than setting up a
symlink, but making a copy simply allows the file in /etc to become
out-of-sync if one updates the files under /usr/share{/lib}/zoneinfo
without re-running tzsetup again.

Re: Fixing DST manually on rel4 & rel5
here is my quick hack script to manually do this
#!/bin/sh
zdump -v /etc/localtime | grep 2007
echo If sun Mar 11 and Nov 1 then OK
echo Otherwise stop script now and rerun from clean temp dir
echo "also ls -l /etc |more and check that localtime is not a link"
sleep 5
fetch ftp://sunrise.ipinc.net/pub/tzdata2007c.tar.gz
tar -xzf tzdata2007c.tar.gz
zic -d zoneinfo northamerica
cp -R zoneinfo/* /usr/share/zoneinfo
zdump -v /usr/share/zoneinfo/PST8PDT | grep 2007
zdump -v /usr/share/zoneinfo/America/Los_Angeles | grep 2007
echo "if localtime is a link then stop and rm /etc/localtime then"
echo "ln -s /usr/share/zoneinfo/PST8PDT /etc/localtime"
sleep 5
cp /usr/share/zoneinfo/PST8PDT /etc/localtime
zdump -v /etc/localtime | grep 2007
echo If Sun Mar 11 and Nov 1 then OK
echo "now rm -r this temp dir"
$
I think the ln-s line is backwards, I didn't check it. I think it's
been a while since they used softlinks for localtime

Copying the zoneinfo files (and running tzsetup) should work fine.
