SYNOPSIS

10       combinedeltarpm  [-v]  [-V  version] [-z compression] [-S signaturerpm]
11       olddeltarpms...  newdeltarpm

DESCRIPTION

15       combinedeltarpm creates a new deltarpm from multiple old ones.   Apply‐
16       ing  the  rsulting deltarpm has the same effect as applying each of the
17       old ones in the  specifed  order.  Use  the  -v  option  to  make  com‐
18       binedeltarpm more verbose about its work.
19
20       combinedeltarpm  normally  produces  a  V3  format deltarpm, use the -V
21       option to specify a different version if desired. The -z option can  be
22       used  to  specify a different compression method, the default is to use
23       the same compression method as used in the last of the old deltarpms.
24
25       If you want to use a different header signature you can also specify  a
26       rpm  with the -S option which will be used as signature reference. This
27       feature can be used to if a deltarpm was made against an  unsigned  rpm
28       which later got signed.

MEMORY CONSIDERATIONS

32       The  implementation of combinedeltarpm currently unpacks the add-blocks
33       of the deltarpms in memory, thus it needs about twice the  uncompressed
34       payload size of the target rpm.
