I think your case is pathological, so to speak. (That doesn't mean I
think *you* are :) ). The policy manual says symlinks within the same
top-level directory (in this case, /usr) should be relative, and absolute
across top-level directories (for instance, the many links out of various
places in /usr/X11R6/lib/X11 into /etc/X11). Lintian checks for this
stuff and what I do is lintian clean. For -4 I added some logic to the
xbase preinst that makes sure /usr/X11R6/lib/X11/doc isn't already a plain
directory, which obviously isn't the case for you. So things look right in
one respect to the package, and if you didn't have /usr/X11R6 mounted from
a different device they'd work fine.
Here's what the preinst does with the file in question:
# ensure canocical location of X11 documentation
for docdir in /usr/doc/X11 /usr/X11R6/lib/X11/doc; do
[ -L $docdir ] && rm $docdir
done
[ -d /usr/X11R6/lib/X11/doc -a ! -L /usr/X11R6/lib/X11/doc ] && rm -r \
/usr/X11R6/lib/X11/doc
# the next line *SHOULD* be redundant, but...
ln -s ../../../doc/X11 /usr/X11R6/lib/X11/doc
And later the postinst does some checks:
# final sanity checks
for file in /usr/X11R6/lib/X11/twm/system.twmrc \
[...]
/usr/X11R6/lib/X11/doc \
/usr/doc/X11/README.Debian \
/usr/lib/X11 \
/usr/bin/X11; do
if [ -e $file ]; then
if [ ! -L $file ]; then
$condecho
echo "WARNING: An error has been found in this installation of the xbase"
echo "package. The file $file"
echo "should be a symlink and it is not. Please file a bug report"
echo "against the xbase package reporting this fact. See"
echo "/usr/doc/debian/bug-reporting.txt for information on filing bugs."

$condecho
echo "WARNING: An error has been found in this installation of the xbase"
echo "package. The file $file"

[ -e filename ] does not evaluate true if filename is a broken symlink, and
for my purposes that's desirable behavior.
I suppose this needs to be taken to the policy group. Either we need to
support folks who have /usr/X11R6 mounted from a different device, or we
need to forbid it. Either way something has to change.
