From 303958dc42d451aead0e1b9cf7b9836831a05f4b Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 26 Oct 2005 01:40:31 +0200 Subject: [PATCH] create_symref: if symlink fails, fall back to writing a "symbolic ref" There are filesystems out there which do not understand symlinks, even if the OS is perfectly capable of writing them. So, do not fail right away, but try to write a symbolic ref first. If that fails, you can die().
