6 makedeltarpm - create a deltarpm from two rpms

10 makedeltarpm [-v] [-V version] [-z compression] [-s seqfile] [-r] [-u]
11 oldrpm newrpm deltarpm
12 makedeltarpm [-v] [-V version] [-z compression] [-s seqfile] [-u] -p
13 oldrpmprint oldpatchrpm oldrpm newrpm deltarpm

17 makedeltarpm creates a deltarpm from two rpms. The deltarpm can later
18 be used to recreate the new rpm from either filesystem data or the old
19 rpm. Use the -v option to make makedeltarpm more verbose about its work
20 (use it twice to make it even more verbose).
21 If you want to create a smaller and faster to combine "rpm-only"
23 deltarpm which does not work with filesystem data, specify the -r
24 option.
25 makedeltarpm normally produces a V3 format deltarpm, use the -V option
27 to specify a different version if desired. The -z option can be used to
28 specify a different compression method, the default is to use the same
29 compression method as used in the new rpm.
30 The -s option makes makedeltarpm write out the sequence id to the spec‐
32 ified file seqfile.
33 If you also use patch rpms you should use the -p option to specify the
35 rpm-print of oldrpm and the created patch rpm. This option tells
36 makedeltarpm to exclude the files that were not included in the patch
37 rpm but are not byteswise identical to the ones in oldrpm.
38 makedeltarpm can also create an "identity" deltarpm by adding the -u
40 switch. In this case only one rpm has to be specified. An identity
41 deltarpm can be useful to just replace the signature header of a rpm or
42 to reconstruct a rpm from the filesystem.
