This can be done quite simple by using the MD5SUMS files, like this:
cp MD5SUMS MD5SUMS.old
rsync server::MD5SUMS .
if diff MD5SUMS MD5SUMS.old ; then
for each image (or: for each CHANGED image) ; do
rsync server::image.list .
make-pseudo-image image.list ftp://server/debian
mv pseudo-image realname
rm -rf pseudo-image*
rsync --block-size=8192 server::realname .
NOTE: updating to a "point" release (like 2.1r2 -> 2.1r3) does not necessarily
require the make-pseudo-image; in that case rsyncing the whole tree may be
easier (incl. slink-test which has hardlinks to the actual images (or vice
versa)). However, if you already have a local debian packages mirror, the
pseudo-image way is faster. And of course it's "the only" way to get major
updates (2.1 -> 2.2).
If you have converted this into something useful, please let me know. This is
not really pseudo-image-kit related, but certainly worth publishing on the web
