Install-script - `/dev/shm/*.old'`

Hi,

Thanks for the fixes - and the script, too.

Maybe it could be a good idea, to remake the "Readme" - i can help, if you like.

Also, i have a question, related to the script.

My Xiaomi Roborock S5/S50 did reset the other day, and today, i installed my custom firmware (again), and started this script.

I saw an issue message, related to rm the old-files.. It's reporting that no files could be found, matching /dev/shm/*.old'

Output:

./install.sh 
Before installing, please check if the cron jobs have not been set yet. Otherwise it will add a different line in /etc/crontab.

Install cron tasks.
cron stop/waiting
cron start/running, process 27389
Modify logrotate.sh to be not as aggressive and delete old log files.
logrotate stop/waiting
logrotate start/running, process 27405
Executing check_reboot script takes aprox. 1 min.
rrwatchdoge stop/waiting
rm: cannot remove '/dev/shm/*.old': No such file or directory
rrwatchdoge start/running, process 27742
ALL DONE!
Please check your robot for function

Maybe, you should just implement -f in the command:

-f, --force
          ignore nonexistent files, never prompt
