NAME

       makedeltarpm - create a deltarpm from two rpms

SYNOPSIS

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

DESCRIPTION

       makedeltarpm  creates  a  deltarpm from two rpms. The deltarpm can later be used to recreate the new rpm from either filesystem data or the
       old rpm. Use the -v option to make makedeltarpm more verbose about its work (use it twice to make it even more verbose).

       If you want to create a smaller and faster to combine "rpm-only" deltarpm which does not work with filesystem data, specify the -r option.

       makedeltarpm 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 new rpm.

       The -s option makes makedeltarpm write out the sequence id to the specified file seqfile.

       If  you	also  use  patch rpms you should use the -p option to specify the rpm-print of oldrpm and the created patch rpm. This option tells
       makedeltarpm to exclude the files that were not included in the patch rpm but are not byteswise identical to the ones in oldrpm.

       makedeltarpm can also create an "identity" deltarpm by adding the -u switch. In this case only one rpm has to  be  specified.  An  identity
       deltarpm can be useful to just replace the signature header of a rpm or to reconstruct a rpm from the filesystem.

NAME

       applydeltarpm - reconstruct an rpm from a deltarpm

SYNOPSIS

       applydeltarpm [-v] [-p] [-r oldrpm] deltarpm newrpm
       applydeltarpm -c|-C deltarpm
       applydeltarpm [-c|-C] -s sequence
       applydeltarpm -i deltarpm

DESCRIPTION

       applydeltarpm  applies a binary delta to either an old rpm or to on-disk data to re-create a new rpm. The old rpm can be specified with the
       -r option, if no rpm name is provided on-disk data is used. You can use -p to make applydeltarpm print the percentage of completion, or	-v
       to make it more verbose about its operation.

       The second an third form can be used to check if the reconstruction is possible. It may fail if the on-disk data got changed (deltarpms are
       created in a way that config file changes do not matter) or the deltarpm does not match the rpm the delta was generated with. The -c option
       selects full (i.e. slow) on-disk checking, whereas -C only checks if the filesizes have not changed.

       Instead	of  a full deltarpm a sequence id can be given with the -s sequence option. Such an id contains all the information that is needed
       to do reconstruction checking.

       Finally information about a deltarpm can be printed with the -i option.

MEMORY CONSIDERATIONS

       applydeltarpm was written to work on systems with limited memory.  It uses a paging algorithm to keep the size of in-core data low and  not
       bring the system in an out-of-memory situation.

EXIT STATUS

       applydeltarpm  returns  0  if  the  rpm could be recreated or the checking succeeded, it returns 1 and prints an error message to stderr if
       something failed.
