However it was caused by a bug introduced in the Debian libc6 package yesterday so it was unlikely to be the cause of your problem. Nevertheless the reason is instructive so read on. Yesterday a broken libc6 package was uploaded which omitted the /lib64 directory[1]. All Debian binaries on x86-64 use /lib64/ld-linux-x86-64.so.2 as the ELF interpreter, so of course this broke absolutely everything. It broke febootstrap because when it tries to run /init, it has to run /bin/sh which in turn has to load the ELF interpreter and all shared libraries that /bin/sh needs. If the ELF interpreter or any shared library is missing, then execl returns errno == ENOENT and you would see the precise error above. This means that if the error above is seen, we need to look carefully to check that /bin/sh exists (or is a symlink to something that exists), _and_ that all dependent stuff it needs exists. I have added[2] a bunch of debugging into febootstrap so that it should be simpler in future to diagnose this sort of error. Rich.
