Re: memory fragmentation by the loader

[hayim@xxxxxxxxxxxxxx]

OK I figured that I need to do:
prelink -r _base_address_ _library_

changing /lib/tls/libc.so.6 to 0x00585000 was easy.
When I tried to move /lib/ld-linux.so.2 to 0x0056c000 (as it is on my other
machine). Things started to go wrong (to say the least :).
the machine didn't even boot.

I recovered the previous location of ld-linux.so.2, but still it is stuck in the
middle of the address space.

How can I relocate ld-linux.so.2, and still have linux run?


Thanks,
 Hayim.
