Hey,

I was going to remove tomcat, as we are not using it for anything but then some gitlab dependencies were shown and I aborted:

[root@telemetry usr]# sudo yum remove tomcat-el-2.2-api-7.0.76-9.el7_6.noarch

Is this ok [y/N]: n
Exiting on user command

tomcat / java do not appear to be used by anything I care about on this server - so I was going to remove them. But the above worried me.

What do you think iwalker please?
