update default-image from current- image fails

[G_W_Albrecht]

Before testing R80.20.25 on my 1550, i decided to upgrade the factory default image from R80.20.10 (992001365) to R80.20.20 (992001869). Since R80.20.10, we have the command

update default-image from current-image preserve-settings <yes | no> [force <yes | no>]

Explanation in CLI Guide is wrong for this command - force yes gives a immediate reboot, force no lets you decide again as a last step:

The system will now reboot.
During this boot, default image will be updated from current image. Save settings as part of the image: yes
Save license as part of the image: yes
Save SIC as part of the image: yes
Are you sure you want to continue (yes/no) ?

Only if you answer yes, the command will execute after reboot. But system logs show:

Anyone seen this before ?

After removing a backup file from /storage/ this command executed successfully,

So now after installing R80.20.25 it looks like this:

So it was a "no more space" rather than an "image corrupted" issue...
