Hi,
Solved the problem with hardened-dev-sources-2.6.7-r3. Have PaX-aslr and
quite full grsec2 - working.
A day or two ago read /ML/ that beside linux-headers there are also
linux26-headers assuming they are nearly stable.
Resolved to rebuild the toolchain - linux26-headers, modutils,
module-init-tools, binutils and glibc with GCC-3.3.4-r1.
Haven't time to try rsbac-dev-kernel-2.6.7-r3 (by zhware)or r1, but i'll
try it later.
Had many problems when booting rsbac-kernels (genkernel-initrd or
manually-no-initrd) made. At last they booted but stopped when mounting
local fs-systems.
Thanks very much.
