They are firstly created by dracut inside the initramfs:
dracut.sh:
for d in dev proc sys sysroot root run run/lock run/initramfs; do
if [ -L "/$d" ]; then
inst_symlink "/$d"
else
mkdir -m 0755 -p "$initdir/$d"
fi
done
and then re-created by kernel:
init/initramfs.c:
static int __init do_name(void)
{
...
clean_path(collected, mode);
...
} else if (S_ISDIR(mode)) {
sys_mkdir(collected, mode);
sys_chown(collected,uid, gid);
sys_chmod(collected, mode);
dir_add(collected, mtime);
}...
...
}
Cheers!
