No awareness needed if one reads the documentation.
Is that not the golden rule of Linux?

OK, I'm not really sure why so far everyone thinks the command line switch is
such a bad idea. Mostly because what I'm reading here the ones
complaining/yelling the most against it don't use it on a daily basis.
YUM is safe. To date, I have not had any issues with YUM. YUM has safeguards
built in that protect the base install of the OS from being updated by a 3rd
party repo, does ATP have this? I don't know as I don't use ATP which means
I am in no position to comment on this.
YUM will install missing dependencies as needed, but again the safe guard will
not allow third party software to replace base OS software. Since YUM does
protect the base OS I have no problems installing software using the "-y"
switch.

We are one big happy family. :)
