Subject: Fix for olllllld bash
X-Git-Url: https://git.sommitrealweird.co.uk//gitweb/?p=rpmbased-dist-chroot.git;a=commitdiff_plain;h=a6e03694cb18f3097f3117e5ec1340a25c46edeb

Fix for olllllld bash

Bash 2.05 does not include the =~ operator for regexps, so we get round this in inventive ways to overcome the shortfallings of a default debian sarge install (I really wish they'd made bash3 the default in that release!)
