Hello. I'm testing version 4.06-pre5. Using the CONFIG + APPEND directive with RELATIVE paths and changing the base directory is sometimes failing. Booting with ISOLINUX is OK but SYSLINUX is not. To demonstrate an example, I have uploaded a little 7z archive containing: _ a little ISO image; _ a 1440KiB floppy image. Both images have the same directory tree and cfg files. The only difference is the respective boot loader. My test: 1_ Boot the ISO image in a VM. 2_ First menu ; press "enter" 3_ Second menu ; press "enter" 4_ Third menu ; press "enter" 5_ Note the exact PWD. 6_ Repeat previous steps for the floppy image. The resulting final working directory for the ISO image is the correct one (equivalent to "/" ); but for the floppy (SYSLINUX) the final working directory doesn't match the expected final working directory (according to the APPENDs in the cfg files). I also tested other directory trees without using menu.c32 and the result was the same: ISOLINUX works OK, SYSLINUX doesn't. BTW, version 4.05 is also failing in the exact same way.

The archive will be available for 7 days. TIA.
