Does this mean the dynamic linker starts with it's GOT pointer as NULL,
initializes that to point it to the malloc in elf/dl-minimal.c, and then,
once libc.so.6 is relocated updates its GOT pointer to point to the malloc
in libc.so.6?


ld.so re-relocates itself after all static dependencies have been loaded
and relocated.

And even at this point, the code is used for future dynamic linkingoperations?


Thanks,
Florian
