Use the +.B -v +option to make combinedeltarpm more verbose about its work. +.PP +combinedeltarpm normally produces a V3 format deltarpm, use the +.B -V +option to specify a different version if desired. The +.B -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. +.PP +If you want to use a different header +signature you can also specify a rpm with the +.B -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 +later got signed. + +.SH 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. + +.SH SEE ALSO +.BR makedeltarpm (8) +.BR applydeltarpm (8) + +.SH AUTHOR +Michael Schroeder <mls@suse.de> |
