@fernando-stteffen Well, I wouldn't wait for a user input. I would write the alllowed time to a config file and read it at boot. Now I don't know your skills in bash, but this should be pretty easy, except you must set this at the previous boot.

There is no cron nor at in recalbox though ... You'll have to write the while loop by yourself

@leok I think 35 ºC is a "low" temperature for RPi. Here, with one fan running all the time, it keeps arround 48 ºC.

It's a known Kodi issue and would require key mapping especially for Kodi to fix it.

Edit your fstab file for the UUID of your HDD partition.  I prefer UUID as it doesn't tend to change by moving drives around.  You can edit the fstab file and change the mount point of the /dev/whatever to UUID=uuid of your partition  /share (partition type without parentheses<span style="line-height: 1.5;">) (options without parentheses)</span> That fixes any problems I've had with things moving around or mounting in the wrong place.
