我从官方的 mars-debian 中 copy 了一份设备树过来，同时参考这个官方 debian 镜像，往我的 NixOS 镜像里补充了 /extlinux/extlinux.conf 中的一些参数，现在系统能通过 extlinux 进入到 starting kernel 阶段了，但是在跑 /init 时会报错：
[ 1.686969] Run /init as init process

[ 44.178799] /dev/disk/by-label/NIXOS_SD: Can't open blockdev
我的存储卡很明确是有 NIXOS_SD 这个分区的，它是 SD 卡的第三个分区，就很奇怪。
另外前面有几个 deferred 的报错会卡一下，貌似是识别有问题了。
详细日志如下：
