Please consider applying the patch forwarded upstream (linked in an earlier control message) soon; this bug means that if the current initramfs is updated, it will no longer boot, as run-init will segfault in klibc. Given sparc64 is not a release architecture I can't make this bug RC, otherwise I'd probably go for critical. (To be clear, the issue is in 2.0.4-10 simply because that is the first upload to happen since sparc64 has had PIE enabled by default in GCC) Regards, James
