Dear All, Could someone give me some pointers. I never had it on CentOS 4,5,6. On freshly installed CentOS 7 ("development workstation" installation type with several extra things) when I log in as root in console I get this message: attempting to create directory /root/perl5 and indeed empty directory /root/perl5 is being created. (And my understanding is that that is done for every user at login). Can anyone point to what does it and what is the rationale behind that. Not that I no not like perl in particular, but I do not like any tweaking of anything happening as a user logs in. Thanks for all your help. And my apologies for being this ignorant person who likely doesn't know some trivial thing...
