I did this. My Computer restarted during the night. I think my droplets are still mining and likely do not need any supervision until the time comes to shut them down?

EDIT: It seems I must keep these windows open for the servers to keep mining. Oh well.

Also, is there a way to change the root password? This must be a totally noob question for all you Linux pros out there, but I am totally new to this...

And thanks!!!

Hi, I did this, and this is showing on my putty screen: After this operation, 14.9 MB of additional disk space will be used.
Do you want to continue [Y/n]? Y
Abort.

Because I am new to this, could you help me to work it out? Thank you.
