From 1e322675f96b4ff4f198b4ec6673059ceb30fbf1 Mon Sep 17 00:00:00 2001 From: Karel Zak Date: Mon, 27 Aug 2007 23:31:25 +0200 Subject: [PATCH] setarch: add --3gb option fot compatibility with Debian linux{32,64} command Debian had a pre-existing linux{32,64} command which supported only --3gb and --4gb. Adding support for those options allows setarch to replace that package. (Note that long options are expected for all setarch flags in the next release.)
