Wow, great. I just reported this as well, but you bisected it already. So seems Debian´s initramfs uses klibc. Appears so: https://wiki.debian.org/initramfs merkaba:/boot> lsinitramfs -l initrd.img-4.0.1-tp520-btrfs-trim-norace+ | egrep "klibc|libc.so" -rwxr-xr-x 1 root root 1729984 Apr 15 02:01 lib/x86_64-linux-gnu/libc.so.6 -rwxr-xr-x 1 root root 71416 Oct 5 2014 lib/klibc-IpHGKKbZiB_yZ7GPagmQz2GwVAQ.so It seems to contain a glibc as well.
