I was trying to link using a custom linker script that contains a non stantards sections for the output. And this sections always ends up at address ``0x0`` no matters where I put it in the script. Linking using gnu ld doesn't have this behavior and gives what seems the logical output for me. I realized I may not need these custom sections but I'm still curious why is it happening and if I'm missing something or if it is a bug
Here's my linking command
```
ld.lld -n -T kernel/arch/x86-64/linker.ld -o sysroot/boot/colibri.kernel <all my objects files> --Map build/kernel.map
```

.bss ALIGN(4K) :

*(.bss)
}
}
```
