No, I didn't change the host requirements, I changed the configuration. Something quite different in my opinion. We had a discussion about this in: http://wiki.linuxfromscratch.org/lfs/ticket/1962 and although that got resolved, I was trying to head off potential future problems. See also the thread starting at: http://linuxfromscratch.org/pipermail/lfs-dev/2008-April/061181.html In the general case, there *may* be problems with mawk for gawk, byacc for bison, or dash or some other sh variant for bash. We don't test them all, so we can't be sure the others work or not. We do know that if those symlinks are made, then these potential issues are taken out of the loop (if the user follows the section, which admittedly many times is ignored). Also, bashisms tend to creep into many scripts. I really don't have a problem with that as long as the header is #!/bin/bash and not #!/bin/sh. However, upstream developers don't always do that. We don't know in advance all the host systems the users may choose, so heading off potential problems is proactive. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
