I've fixed a silly bug found by Manty when creating HFS hybrid images - the template code interacted badly with the HFS data and sizes were calculated wrongly. It would be nice if jigdo would actually print useful error messages rather than simply "Invalid template data - corrupted file?" in all the places where it checks the template file. Some context helps!

I've also cheated a little to cope with boot files being moved from their normal path (as on the mirror) to /install. I already have MD5 sums supplied up front for those files in the mirror, so when looking for files to jigdo encode I can match up checksums very cheaply and replace the /install path with the real one.

In my testing for JTE 1.9, I'm still creating template files orders of magnitude faster than jigdo-file. But now JTE is also producing smaller template files too. The following sizes are for i386 DVD#1:

sledge:/mirror$ ls -alU OLD.1/sarge-i386-1.* NEW.1/sarge-i386-1.*
-rw-r--r--  1 root root  159395 Aug 27 03:40 OLD.1/sarge-i386-1.jigdo
-rw-r--r--  1 root root 6357306 Aug 27 03:41 OLD.1/sarge-i386-1.template
-rw-r--r--  1 root root  103924 Aug 29 04:54 NEW.1/sarge-i386-1.jigdo
-rw-r--r--  1 root root 3375212 Aug 29 04:54 NEW.1/sarge-i386-1.template

NOTE: the JTE patch to mkisofs needs to be applied AFTER debian patches have been applied during the package build process, as that's easiest for people who want to use the rest of the Debian-applied patches too.
