I agree.  Actually, considering that the info files are stored in just a
single well-known directory, /usr/share/info(*), and further considering
that updated files are rewritten when overwritten, shouldn't it be entirely
sufficient if the update_info_dir script performs a simple test like this:

- Does /usr/share/info/dirs exist?

   No -> run install-info

   Yes -> Is /usr/share/info/dirs mtime < /usr/share/info mtime?

          No -> Do nothing

	 Yes -> run install-info

So, this is actually quite straightforward to write, and /etc/postinstall/0p_update-info-dir.sh becomes the attached.

Can this be relied on for all possible file systems?

Not on FAT.  But then again, FAT is not really a filesystem, rather just
a failed try.

But yes, this does nothing useful if /usr/share/info is on a FAT filesystem, as the mtime doesn't change.
