...e the temporary file so that there was no way to accidentally leave it behind. On linux there is O_TMPFILE, which allows us to create a file with no name in the file system. A name can be given with linkat. Unfortunately we can't use linkat(fd, "", AT_FDCWD, "destination", AT_EMPTY_PATH) Without special permissions and have instead to depend on proc: linkat(AT_FDCWD, "/proc/self/fd/<num>", AT_FDCWD, "destination", AT_SYMLINK_FOLLOW) Another annoyance is that linkat will not replace the destination and renameat2 doesn't support AT_EMPTY_PATH....

See also the description of > AT_EMPTY_PATH flag for fstatat(2) and related syscalls. Hmm? I?ll have to test it.

When booting a recently compiled Xen 4.2 on Ubuntu 12.04, dom0 crashes. I''ve included a serial console log below. I''ve used: Xen 4.2 unstable rev. 25483, compiled on the same machine.
