-# XXX: The gzip package in Debian at some point acquired a Debian-specific
|
|
-# --rsyncable option via a vendor patch. Which is not present in most of the
|
|
-# major distributions, dpkg downstream systems, nor gzip upstream, who have
|
|
-# stated they will most probably not accept it because people should be using
|
|
-# pigz instead.
|
|
+# If gzip supports --rsyncable (version >=1.7 or the Debian patched variant),
|
|
+# we use it. Sadly a non-compliant gzip will not complain about the argument
|
|
+# when it does not understand it, so we can only print out the usage and infer
|
|
+# --rsyncable support from that.

|
|
-# This option should have never been accepted in dpkg, ever. But removing it
|
|
-# now would probably cause demands for tarring and feathering. In addition
|
|
-# we cannot use the Dpkg::Vendor logic because that would cause circular
|
|
-# module dependencies. The whole affair is pretty disgusting really.
