Rock64 no longer boots after dist-upgrade

[KernelPanic]

You are right, forgot the efi parition

Something weird seems to be going on with the one that's mounted by default (or I just don't understand

Code:

rock64@rock64:/mnt/efimmc$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            2.0G     0  2.0G   0% /dev
tmpfs           393M  5.4M  388M   2% /run
/dev/mmcblk1p7   15G  1.6G   13G  12% /
tmpfs           2.0G     0  2.0G   0% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           2.0G     0  2.0G   0% /sys/fs/cgroup
/dev/mmcblk0p6  100M   50M   51M  50% /boot/efi
tmpfs           393M     0  393M   0% /run/user/1000
/dev/mmcblk0p7   29G  9.3G   18G  35% /mnt/bootmmc
/dev/mmcblk1p6  100M   24M   77M  24% /mnt/efimmc

The following two especially:

Code:

/dev/mmcblk1p7   15G  1.6G   13G  12% /
/dev/mmcblk0p6  100M   50M   51M  50% /boot/efi

mmcblk1 = sdcard
mmcblk0 = emmc

So am I right in saying it mounts the wrong efi by default?
I didn't notice at first and mounted what I thought was the emmc to my own mount point (/mnt/efimmc) but ended up copying the same files back and forth   
After still not being able to boot I noticed, rebooted, remounted the sdcard efi to /boot/efi and mmc to /mnt/efimmc copied and BAM we're back in action!

Thanks a lot for pointing me in the right direction!

Could it be that copying the /boot/ and /boot/efi messed something up with my build?

Everything is working as before except for openvpn which can't initiate a connection anymore
ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)

I checked, and indeed there is no /dev/net folder
