Change the rules for all the Debian distribution because you find that 'command -v' is handy, seems quite excessive to me... the problem is there is no better replacement for 'command -v'. And we do not really need an exception -- every shell we have supports this. So the only way a person can end up with a broken system is by installing a shell by hand from somewhere else.

You need to stop hitting the hooch and start thinking more about what Debian is trying to accomplish. Over six hundred packages already use it, it prevents the hard-coding of paths into maintainer scripts and thus renders them more robust against harmless changes in other packages (e.g., moving traceroute from /usr/sbin to /usr/bin) and is otherwise useful. I am far from the only package maintainer who employs this tool. -- G. Branden Robinson| I came, I saw, she conquered.

Does Debian explicitly support such a configuration? That's the point. I can symlink /bin/sh to /usr/bin/tcsh or /usr/bin/X11/XFree86 if I want, but that doesn't mean that the Debian packaging infrastructure offers to it for me via a debconf question, update-alternatives, or some similar mechanism. -- G.

This is relevant how? Policy is not being followed. In sid, we can easily change policy, or we can easily change package scripts. In woody, anyone who links /bin/sh to a shell allowed by debian-policy, whether Debian zsh or a shell which they have compiled themselves, may be suddenly deprived of installed documentation and other random things. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: Bug#148172: command -v in postinsts violating policy
That's different and more fragile: it relies on a fixed path which command -v does not. Is this important in the event that install-docs gets moved, or so that someone can put a different install-docs in the PATH? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Simple suggestion: all Debian install scripts require /bin/bash. They never refer to /bin/sh. Especially as in, #! /bin/sh Or if you don't like bash, ash. If not ash, csh. busybox. perl. Something. Just specify it and be done with it. And demand that shell be installed for the install scripts to run. -- .:. Bryan W.

It also makes it easier to do Stupid Package Tricks like post- processing packages to install into /opt/debian/ (on a non-Debian system, of course), where the path is /opt/debian/bin:/opt/debian/usr/bin.
