--without-sendmail : Fcron does not require an MTA to run but will use one, if it is installed, to email you the results of the fcron script. If you wish to utilize this feature change the switch to --with-sendmail=[path to your MTA] . --with-answer-all=no : After the files are installed, the make install script enters into a configuration routine. The first test will be whether to install a boot script in the /etc/rc.d/init.d directory with the appropriate symbolic links in runlevels 2, 3, 4, and 5. The second is to stop any current fcron processes and start a new one. Since this is probably your first install and we want a boot script based upon the BLFS template we answer 'n' to both tests. --with-dsssl-dir=/usr/share/sgml/docbook/dsssl-stylesheets-&docbook-dsssl-version; : Can be added if you have installed OpenJade and dsssl-stylesheets to generate the documentation from the DocBook source files.
