[CentOS] attempting to create directory /root/perl5

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...

Sincerely yours,
Valeri
