Subject: Blowing away devfs-created /dev/root

Hi, Al. Looking 2.4.19-pre2 I came across this in init/do_mounts.c:
sys_chdir("/dev");
sys_unlink("root");
sys_mknod("root", S_IFBLK|0600, kdev_t_to_nr(ROOT_DEV));

(line 354 onwards). This will have the effect of blowing away the
/dev/root symlink that is carefully created a few lines above. Is
there a reason you did this, rather than something like:
sys_chdir("/dev");
if (do_devfs)
sys_mount("devfs", ".", "devfs", 0, NULL);
else {
sys_unlink("root");
sys_mknod("root", S_IFBLK|0600, kdev_t_to_nr(ROOT_DEV));
}

Regards,

Richard....
