DESCRIPTION

17       fragiso can be used to convert an iso file into a fragment file,  which
18       is  a  list describing all of the rpms on the iso and a data chunk con‐
19       taining everything but the rpms. It is used by  drpmsync  when  an  iso
20       needs to be transferred. The idea is that often the rpms on the iso are
21       already available on the destination host, so  it  saves  bandwidth  to
22       first  transfer  the  fragmented  iso, copy the locally available rpms,
23       transfer the unavailable rpms and reassemble the iso file.
24
25       fragiso make converts the iso into the fragment iso, fragiso  list  can
26       be  used  to  extract the rpm information. This information consists of
27       the offset and length of all rpms and the lead/signature header  md5sum
28       plus  the  header/payload md5sum. To reassemble the iso one has to copy
29       the rpms at the right offset into a new file and then use fragiso  fill
30       later  on  to provide all data not contained in the rpms. The -m option
31       tells fragiso to print the resulting md5sum of the iso to  stdout.   It
32       can be used for verification purposes.
