[syslinux] Location and name of configuration files

[Kim Mik]

It would also be nice, that syslinux and derivates, will look for a config file at the directory where syslinux is installed.

syslinux -d /some/directory/ /dev/sda1

will try to find /some/directory/syslinux.cfg first.

Also a new keyword CD can be handy when you want to make a multiboot CD/USB/... from different distro's.

The CD keyword will make the directory that is given after it, the new main directory, so you don't need to adapt all relative paths.

$ ls /some/directory/distro1
boot.msg
bzImage
initrd

===============================
CD /some/directory/distro1

DISPLAY boot.msg

KERNEL bzImage
APPEND initrd=initrd.gz some parameters
===============================




$ ls /some/directory/distro2
boot.msg

bzImage

initrd

===============================
CD /some/directory/distro2

DISPLAY boot.msg

KERNEL bzImage
APPEND initrd=initrd.gz some parameters
===============================

Yes, I'm seriously thinking that having all derivatives fall back to
syslinux.cfg is the right thing to do.  It won't happen for 3.81 (it's
way too late to make that change), but expect to see it in a future release.
