combindeltarpm - combine multiple deltarpms to a single one
combinedeltarpm creates a new deltarpm from multiple old ones.
Applying the resulting deltarpm has the same effect as applying
each of the old ones in the specified order. Use the
option to make combinedeltarpm more verbose about its work.
combinedeltarpm normally produces a V3 format deltarpm, use the
option to specify a different version if desired. The
option can be used to specify a different compression method, the
default is to use the same compression method as used in the
last of the old deltarpms.
If you want to use a different header
signature you can also specify a rpm with the
option which will be used as signature reference. This feature can
be used to if a deltarpm was made against an unsigned rpm which
later got signed.
The implementation of combinedeltarpm currently unpacks the
add-blocks of the deltarpms in memory, thus it needs about twice
the uncompressed payload size of the target rpm.
