I usually test the netinst image. I'm surprised that netboot use more memory, since it's supposed to fetch only what it really needs. And PXE is supposed not to change much since in the end it's supposed to be the same vmlinuz/initrd as non-pxe. I didn't know about rootskel setting DEBCONF_DROP_TRANSLATIONS, that should probably be coordinated with lowmem's management of low-memory heuristics. And at any rate, 1536M RAM looks really a *lot* to me, it really looks to me like some bug somewhere. Samuel
