# root image is done, tarball it
cd ../../
sudo tar cf unmatched-root.tar unmatched-root/
# put unmatched-root.tar on webserver for Unmatched to wget
# put sda1 sda2 sda3 for Umatched to wget
dd if=sda1 of=/dev/nvme0n1p1
dd if=sda2 of=/dev/nvme0n1p2
dd if=sda3 of=/dev/nvme0n1p3 status=progress

```

# On the Unmatched
Log in via serial to the default Unmatched image.

## Get root tarball
wget http://192.168.1.1/unmatched-root.tar
sync

## Partition nvme drives
Set up partions similar to sd card:
```
root@unmatched:~# fdisk -l /dev/mmcblk0
...
Device          Start      End  Sectors  Size Type
/dev/mmcblk0p1     34     2081     2048    1M HiFive Unleashed FSBL
/dev/mmcblk0p2   2082    10273     8192    4M HiFive Unleashed BBL
/dev/mmcblk0p3  16384   282623   266240  130M Microsoft basic data
/dev/mmcblk0p4 286720 13918207 13631488  6.5G Linux filesystem
```

```
fdisk /dev/nvme0n1
# g for GPT partition
# n for new partion
# 1 for partition 1
# 2048 for first sector
# +1M for size
# t for type
# 107 for HiFive Unleashed FSBL

# 2 for partition 2
# 4096 for first sector

# 4 for partition 4
# 278528 for first sector

# w for write and exit

# format the thing:

# set the time or tar complains:
