NAME

       combindeltarpm - combine multiple deltarpms to a single one

SYNOPSIS

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

DESCRIPTION

       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 -v option to make combinedeltarpm more verbose about its work.

       combinedeltarpm normally produces a V3 format deltarpm, use the -V  option  to  specify  a
       different version if desired. The -z 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 -S
       option which will be used as signature reference.  This  feature  can  be  used  to  if  a
       deltarpm was made against an unsigned rpm which was later signed.

MEMORY CONSIDERATIONS

       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.
