<p>FreeBSD 3.0 and later will have 16 character names, however. <p>In FreeBSD 3.0 and later, the maximum name length has been
increased to 16 characters and those various utilities with
hard-coded name sizes have been found and fixed. The fact that this
touched so many areas of the system is why, in fact, the change was
not made until 3.0.</p>
<p>If you're absolutely confident in your ability to find and fix
these sorts of problems for yourself when and if they pop up, you
can increase the login name length in earlier releases by editing
/usr/include/utmp.h and changing UT_NAMESIZE accordingly. You must
also update MAXLOGNAME in /usr/include/sys/param.h to match
the UT_NAMESIZE change. Finally, if you build from sources, don't
forget that /usr/include is updated each time! Change the appropriate
files in /usr/src/.. instead.</p>
