Hi! I installed the 6.2-RC1 version but now I have decided to remove
the profiled libraries and I know that for that purpose I have to add
the line "NO_PROFILE=" to the make.conf before the "make world"
action.

My doubt is if I reinstall or upgrade the Userland without this option
or anyone (let's say Kerberos, Sendmail.. etc) that I have already
installed, these options are going to be removed, or simply are not
going to be upgraded and/or reinstalled again.

Assuming I have read you correctly, when you put
NO_PROFILE=
NO_SENDMAIL=
et al
into you /etc/make.conf that buildworld (and by extension
installworld) skip over these, leaving the old versions
untouched.  For example, as I have many of those set
in /etc/make.conf ls -l /usr/sbin gives me in part:

-r-xr-xr-x  1 root  wheel      35884 Nov 21 22:25 mtree
-r-xr-xr-x  2 root  wheel    1359316 Feb  1  2006 named
-r-xr-xr-x  1 root  wheel    1060104 Feb  1  2006 named-checkconf
-r-xr-xr-x  1 root  wheel    1011336 Feb  1  2006 named-checkzone
-r-xr-xr-x  2 root  wheel       1738 Feb  1  2006 named.reconfig
-r-xr-xr-x  2 root  wheel       1738 Feb  1  2006 named.reload
-r-xr-xr-x  1 root  wheel       6688 Nov 21 22:26 ndis_events

Where you can see that, although I have rebuilt world as of
21 Nov, since I have NO_BIND= set, the /usr/sbin/named*
has not been touched since 01 Feb.  I suppose they could be
deleted, but AFIK the buildworld/installworld cycle will not do
this for you.

On the other hand, if you are not cramped for space they do
(generally) no harm.

On the gripping hand, a malicious user might be able to start
up and then exploit known bugs in those services, so you may
be better off either upgrading to known good versions or
deleting them.
