I just tested the patch against installworld/kernel and got:

% make installworld|grep symbolic
/usr/share/locale/sr_YU.UTF-8/LC_MONETARY is a symbolic link not modified
/usr/bin/lp is a symbolic link not modified
/usr/bin/lpq is a symbolic link not modified
/usr/bin/lpr is a symbolic link not modified
/usr/bin/lprm is a symbolic link not modified

% make installkernel|grep symbolic
[no output]


Except for the 4 /bin/lp* enteries (which the patch is meant to
preserve) the only issue seems to be
/usr/share/locale/sr_YU.UTF-8/LC_MONETARY.   Thus conclusion so far is
the patch will not harm 8-Current.
