Hello, The latest glibc upload, 2.21-5 failed to build: # Link to any headers found in the old locations first find /usr/include/sys -mindepth 1 \ -exec ln -sf '{}' debian/include/sys ';' find: `/usr/include/sys': No such file or directory So it looks like there are no /usr/include/sys files any more in the kernel headers? If so we can just drop the statement. If you want to keep backward compatibility, we can also make the statement failure non-fatal. Samuel
