+/etc/ikiwiki/auto.setup tries to get abs_path of a non-existent "repository" path, and that doesn't work in my perl:
+
+[mort@localhost ~]$ perl -e 'use Cwd q{abs_path}; print abs_path("/var")'
+/var[mort@localhost ~]$ perl -e 'use Cwd q{abs_path}; print abs_path("/abcde")'
+[mort@localhost ~]$ 
+
+Because of this, /etc/ikiwiki/auto.setup fails: 
+
+$ ikiwiki -setup /etc/ikiwiki/auto.setup
+What will the wiki be named? wiki
+What revision control system to use? git
+What wiki user (or openid) will be admin? mort

+Can't ikiwiki's "make test" perhaps test for this, so that one knows something will go wrong?
