# Figure out if we think that /etc/gconf/2/path has been intentionally
# modified by the user

#  1: User modified /etc/gconf/2/path.debathena, but left the path ->
#     path.debathena symlink in place
#  2: User changed the /etc/gconf/2/path symlink
#
# We have to figure out what's going on before undoing the diversion
# (which will happen in the debhelper block). But we can't actually do
# anything about it until afterwards, because of ucf's broken symlink
# handling.
