It is used by +.B drpmsync +when an iso needs to be transfered. The idea is that often the rpms +on the iso are already available on the destination host, so it saves +bandwith to first transfer the fragmented iso, copy the locally +available rpms, transfer the unavailable rpms and reassemble the +iso file. + +.B fragiso +.B make +converts the iso into the fragment iso, +.B fragiso +.B list +can be used to extract the rpm information. This information consists +of the offset and length of all rpms and the lead/signature header +md5sum plus the header/payload md5sum. To reassemble the iso one +has to copy the rpms at the right offset into a new file and then +use +.B fragiso +.B fill +later on to provide all data not contained in the rpms. The +.B -m +option tells fragiso to print the resulting md5sum of the iso to stdout. +It can be used for verification purposes. + +.SH SEE ALSO +.BR drpmsync (8) + +.SH AUTHOR +Michael Schroeder <mls@suse.de> |
