Hi Stefan I had two consecutive KStars crash creating a dark library but after rebooting no more issues trying to replicate the crash.
Now I have about 250 darks with various gain sets and durations with no issues.
I hope in a test under the stars soon too.

Thanks Mattia, I can confirm

Is it possible / a good idea saving in temperature and heater status in camera configuration?

Oh, yes, your are right, wrong screenshot.
It happens with the correct gain too:

But I can't use the library

I can’t get the dark library to work: the library appears to be created, but when I try to use it capturing an image I get the message "No suitable dark frames or defect maps found. Please run the Dark Library wizard in Capture module."
I’m using KStars v3.6.2
Here a sequence of what I do.

5) define the boot order
now I can set the boot order with the command:

sudo raspi-config

chosing Advanced options > Boot Order

6) set the root PARTUID of SSD
On SSD I can now set the new PARTUUID for root volume:

sudo nano /boot/cmdline.txt

and replace the SD PARTUUID to the SSD PARTUUID:
~~root=PARTUUID=9efc3dd8-01~~ root=PARTUUID=0860e500-02

7) define the mount point on SSD

sudo nano /etc/fstab

Now, rebooting I have this:

astroberry@astroberry:~ $ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    0 465.8G  0 disk 
├─sda1        8:1    0   256M  0 part /boot
├─sda2        8:2    0 146.5G  0 part /
└─sda3        8:3    0   319G  0 part /media/astroberry/astrofoto
mmcblk0     179:0    0 116.2G  0 disk 
├─mmcblk0p1 179:1    0   256M  0 part /media/astroberry/boot
└─mmcblk0p2 179:2    0 115.9G  0 part /media/astroberry/rootfs

where "sda" is the SSD and "mmcblk0" is the SD.
If I remove the SSD it boots with SD and I have:

astroberry@astroberry:~ $ lsblk 
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
mmcblk0     179:0    0 116.2G  0 disk 
├─mmcblk0p1 179:1    0   256M  0 part /boot
└─mmcblk0p2 179:2    0 115.9G  0 part /

The speed is improved:

I had a 500 GB SSD used as cache on my NAS but the estimated lifespan was going too down so I’ve replaced it.
Now I’m using the SSD in an USB enclosure attached to Raspberry Pi 4 to boot Astroberry, but due to low estimated lifespan (1%), (and because I don’t know where to store the Astroberry microSD without loosing it ) I’ve set the microSD as fallback.
Here how I’ve made it.
