NAME¶
fragiso - split rpm packages from an iso and reassemble the iso later on
SYNOPSIS¶
fragiso make iso fiso
fragiso list fiso
fragiso fill [
-m]
fiso iso
DESCRIPTION¶
fragiso can be used to convert an iso file into a fragment file, which is a list
describing all of the rpms on the iso and a data chunk containing everything
but the rpms. It is used by
drpmsync when an iso needs to be
transferred. The idea is that often the rpms on the iso are already available
on the destination host, so it saves bandwidth to first transfer the
fragmented iso, copy the locally available rpms, transfer the unavailable rpms
and reassemble the iso file.
fragiso make converts the iso into the fragment iso,
fragiso 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
fragiso fill later on to provide all data not contained in the
rpms. The
-m option tells fragiso to print the resulting md5sum of the
iso to stdout. It can be used for verification purposes.
