I just hit the same thing without using sysupgrade.

Essentially tar built in I'm not sure which window can't unpack symlinks.

On a couple of days old -current/amd64

grab base.tar.xz
tar -tzvf base.tar.xz | grep reboot        see that it's a symlink
tar -xzpvf base.tar.xz -C /                see that /sbin/reboot is a zero
                                                 length file
cd / && pax -r -v -z -pe -f base.tar.xz    see that /sbin/reboot is fine

Oddly - now repeat the tar, and also find that it is fine.

So the work around seems to be "use pax". The surpise is that then tar is
fixed.
