delta/syslinux.git/com32, branch syslinux-5.02-pre1 git.kernel.org: pub/scm/boot/syslinux/syslinux.git elflink: Use CurrentDirName for initial PATH if valid 2013-02-07T18:09:13+00:00 Matt Fleming matt.fleming@intel.com 2013-02-07T17:56:24+00:00 282fe9da42ebb0c34cf4256972a8c07ba5542e23 commit c250a42263c8 ("elflink: Set PATH to the directory containing ldlinux.c32") made the mistake of thinking that CurrentDirName doesn't contain useful data for PXELINUX, it may do. If a user specifies a Path Prefix (DHCP option 210) we enter load_env32() with that path as the current working directory. If that path is thrown away instead of being used for PATH we may fail to load a config file as specified with Configuration File Option (DHCP option 209).

We need to explicitly invoke the function to initialise __syslinux_serial_console_info once we've parsed any config files. eprintf.c was introduced in commit 086d698c642f ("ldlinux: Add eprintf() to print to VGA and serial") because printf() output wasn't appearing on the serial console.
