But a well documented mess.  That is basically consistent with the FHD
(Filesystem Hierarchy Standard).  Same old thing as the FSSTD, they just
changed the name.

Some eople get grumpy if you fail to follow the standard.

Sort of conflicting.  Only distros are allowed to install into /usr.
User installed stuff is supposed to go in /usr/local/

So it the package come from NTPSec, it has to go in /usr/local.  But
when a distro repackages it they have to put it in /usr/

/etc/alternatives is totally non-standard.  Better to replace the old
versions in /usr with links to /usr/local/.  Or, maybe instead a script
to hunt out older ntpd's.  A lot of programs do this, you find out when
your install is taking forever and the installer is searching all your
NFS shares. :-(
