+There is no need to have a relocation section that nothing points at.
+The image is still seen as relocatable as long as the Characteristics of

+leading to unpredictable bugs.

+
+I'm not 100% positive about the uselessness of the relocation section. However:
+1) it works on my real hardware;
+2) OVMF doesn't check the section headers at all;
+3) all the docs I could find say that the section names are arbitrary;
+4) the only way to make the relocation actually happen is by setting the
+base_relocation_table field of the extra headers to point to this section;
+5) The right way to indicate the image is not relocatable would be by setting
+the characteristics IMAGE_FILE_RELOCS_STRIPPED in the coff header.
+
+Moreover, the relocation entry cannot be inserted before the end of the headers
+(512 bytes), this mean we would have to push everything a few bytes further.
+And I think it's better if it can be avoided. :)

+
+In the ELF format, only the program headers are reliable to determine

+The .bss section should always be marked as NOLOAD for ld since its

+
+Signed-off-by: Celelibi <celelibi at gmail.com>
+---
+
+Again, I'm not 100% positive about the semantics of NOLOAD in a linker script.
+However I found this make things work better.
+Actually the file core/fs/fs.o have a .bss16 section that is not empty. If I
+understood correctly, only .bss can be empty in a .o. Thus ld generates the
+zeros that belong to that section in the .o. Then, when merging the section
+.bss16 into the .bss of syslinux.so, ld is forced to generate ALL the zeros
+that belong to the .bss section. Marking this section as NOLOAD make ld to
+ignore its content but still produce a PT_LOAD program header with the right
+memory size, as needed for the bss.
