Question on /etc/make.conf for upgrade to 4.8R

[Lin Jianfong]

I'm wondering about this group of options :

# To avoid building various parts of the base system:
#NO_CVS=  true  # do not build CVS
#NO_BIND= true  # do not build BIND
#NO_FORTRAN=  true  # do not build g77 and related libraries
#NO_I4B=  true  # do not build isdn4bsd package
#NO_IPFILTER= true  # do not build IP Filter package
#NO_LPR=  true  # do not build lpr and related programs
#NO_MAILWRAPPER=true  # do not build the mailwrapper(8) MTA selector
#NO_MODULES=  true  # do not build modules with the kernel
#NO_OBJC= true  # do not build Objective C support
#NO_OPENSSH=  true  # do not build OpenSSH
#NO_OPENSSL=  true  # do not build OpenSSL (implies NO_OPENSSH)
#NO_SENDMAIL= true  # do not build sendmail and related programs
#NO_SHAREDOCS=  true  # do not build the 4.4BSD legacy docs
#NO_TCSH= true  # do not build and install /bin/csh (which is tcsh)
#NO_X=    true  # do not compile in XWindows support (e.g. doscmd)
#NOCRYPT= true  # do not build any crypto code
#NOGAMES= true  # do not build games (games/ subdir)
#NOINFO=  true  # do not make or install info files
#NOLIBC_R=  true  # do not build libc_r (re-entrant version of libc)
#NOPERL=  true  # do not build perl. Disables OpenSSL optimizations
#NOPROFILE= true  # Avoid compiling profiled libraries
#NOSECURE=  true  # do not build crypto code in secure/ subdir
#NOSHARE= true  # do not go into the share subdir
#NOUUCP=  true  # do not build uucp related programs

Aren't some of the parts of the base system supposed to be upgraded along, 
such as tcsh, bind, cvs, lpr, etc or are they not really part of the base 
system ? I'm planning to upgrade a 4.7 box to 4.8.

Thanks.
