Change Details

As in the old nextboot.sh script: - First write everything to a tempfile instead of /boot/nextboot.conf. - fsync() the tempfile before renaming it to nextboot.conf. While here fix some other nits: - Don't hard-code the dirname of the "fn" parameter in write_nextboot(). - Use err/errx/errc() instead of E(). In those error paths it doesn't make sense to continue even if "force" is set. Fixes: fd6d47375a78 ("rescue,nextboot: Install nextboot as a link to reboot, rm nextboot.sh")
