Hello, I'd like to suggest that scripts, debian.rules etc... use gunzip -c instead of zcat when the intent is to get the contents of a gzipped file on stdout. This is because if binaries from a BSD compress package (not necessarily built with compress-package) will make a true zcat available on the system, which of course cannot handle gzipped files. IMO, zcat means `cat a compressed (.Z) file', because that's what it does for years. The fact that /bin/zcat on Debian systems also handle gzipped files is a convenience for the user, but in no case guarantee scripts that the first available zcat in $PATH will be able to do so (and again zcat is not the best name for such a command due to historic heritage).
Is this something unreasonable to ask? Yves.
