Hello Experts!

I'm sure many of you run CentOS for some time already.

My question is: is there some place that lists which of the most often 
used sysadmin commands are gone and what are replacements for them. Or 
what else one needs to do after successful installation. (in the past it 
was process accounting that was not enabled by default, but which gives 
you quite some handle in investigating compromise).

I just tried quite ordinaly command of freshly installed CentOS 8:


and got an error:

last: (default utx db): No such file or directory

I realize that it could be just me, and I'll cope with that myself one 
way or another but this one prompted me to ask everybody: Is there 
anything I can read so I can learn what differenmt to expect on CentOS 8 
from, say, CentOS 7?
