This is for FreeBSD-current, as of June 1.
The tcpmux-related code in inetd.c:main() has a bug: a for loop variable
(sep) is set to NULL by code within the loop. When the loop is continued
and sep->se_next is referenced, the program crashes. One possible fix
follows.
Also, a line like:
tcpmux stream tcp nowait root internal
should perhaps be put in /etc/inetd.conf so that tcpmux services can be
started. The man page mentions tcpmux/servicename lines, but doesn't make
it clear that the tcpmux service itself must be listed.
Lastly, the Send-pr line in /usr/share/info/dir should have a period
where the second colon is:
* Send-pr: (send-pr).

Thank you for a *fine* system.

Unaffiliated and loving it.
