 while your idea might look nice in the first place, I see a lot problems
 with that solution. I think you're already aware of the security risks
 of your hack.
 Your config instructs inetd to set verbose debugging mode, bind to a
 specific IP address and write it's pidfile to /tmp. It is not guaranteed
 (and by default not the case) to have 1) syslogd running in single user
 mode and 2) the network interfaces are up.
 Also inetd lives in /usr/sbin, needs libs from /usr/lib, telnetd lives
 in /usr/libexec and also needs libs from /usr/lib. In single user mode
 the only filesystem mounted will be the root-fs and it's mounted
 read-only. syslogd logs by default to /var/log.
 Please make sure, filesystems root-fs, /usr, /var and /tmp are mounted
 and /tmp and /var are writable, syslogd is started. If you can make sure
 all these conditions are met, please check if you can reproduce this. If
 the problem persists, we need ktrace debug output.
 Also when logging in and out, login(1) tries to write wtmp which may
 also fail with r/o mounts.
 Please keep in mind, your solution should not be used in the public network.
