From 7718b19389fd02407860ce587196adc04f80bb5d Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Wed, 27 Aug 2008 17:20:25 +0000 Subject: [PATCH] * Explicitly set PWD to prevent problems with chroot builds. In particular, dietlibc cannot figure out the cwd because the inode of the current directory doesn't appear in ..
