7.1. jigdo-easy
Jigdo-easy, by Anne Bezemer, is a fork from jigdo-lite which is portable to a wider
range of systems, including Microsoft Windows, old SunOS, HP-UX and IRIX). It's also easier
to use than jigdo-lite but because of changes made to Jigdo, will only work with Potato and
Woody. Jigdo-easy will not be able to download Sarge and Sid. See Section 7.4 and
Section 6.13.
7.3. jigdo-file-cache.db
The cache contains the md5sums of files read when you supply a directory at the
Files to scan: prompt. If you have jigdo-file scan the same directory a
second time, the scan will be very fast.
This could be useful in the following case: rev0 gets updated to rev1. With the rev1 CD
images, some packages may have been pushed from CD n to CD
n+1, or vice versa. If you had a particularly slow link (e.g. modem),
you'd try to avoid downloading these packages again. For this reason, when downloading the
new version of CD n, you'd let jigdo-lite scan the three CDs
n-1, n and n+1 (or even all 8 CDs if
you want to be 100\% sure).
If you have jigdo-lite scan the same CDs over and over again while updating each of the
8 CD images, the cache will prevent all the data on the CDs from being read multiple
times.
The cache is much more important when generating jigdo files,
because you don't want jigdo-file to read in your whole 50GB Debian mirror for every generated
jigdo file.
