[Discuss] Crash / Reboot

[John Blomfield]

Hi Alan,

Thanks for the link. dnf is the command line package manager for Fedora 
replacing Yum. It put me on the right path. dnf.config file allows one 
to set the number of kernels to retain (default is 3) so I've increased 
the number to 6 which should cover future kernel upgrades. I have to do 
more research to find an option for retaining a specific kernel version 
irrespective of the number of upgrades.

John
