It take the libpng-source to replace the current syslinux code.
The point is syslinux is a bootloader that obviously don't share libs
with the rest of the system.
Considering that we can attack the bootloader via a picture means you
compromized the picture. If you can change the picture located at /boot,
means that you can compromize the booting parameters too.
So if we take this road of removing bootloader's libs, shall we also
remove the jpeg/gz/gcc/... libs too, and maybe for other bootloaders too ?
I do understand the need for the application that runs under linux...
but about the bootloaders...
What's your thoughts about it ?
Would you agree on keep syslinux untouched regarding the png lib ?
