This was actually brought this up on the ccache mailing list recently: http://www.mail-archive.com/[email protected]/msg00754.html. I still think that not failing silently is a good thing in general, but having a special exception for HOME=/dev/null could perhaps be a good idea. On the other hand, if ccache disables itself when HOME=/dev/null (and when CCACHE_DIR isn't set explicitly), you won't get the chance to know that you need to set CCACHE_DIR to use ccache when compiling autogen... > The fact that it tries to to so even with CCACHE_DISABLE=true is > broken, isn't it? Yes, that's a bug. It will be fixed in ccache 3.2. -- Joel
