Summary:                    inetd does not set argv[0]
Description: 
When inetd (1.01) calls a service handler it doesn't set argv[0], which
obviously makes e.g. busybox telnetd fail to work. Attaching a patch.

No. Its special for wrappers and documented:

     The server program arguments should be just as arguments normally
are,
     starting with argv[0], which is the name of the program.

See manuals for BSD inetd(8)
 
Please close this bugreport.

Well, yes, they should be, but the point is they aren't.
argv[0] is NULL.

A trivail test from busybox tree:
$ echo "
2121  stream  tcp     nowait  `id -un`    `pwd`/busybox  ls
" > inetd_test.conf

$ ./busybox inetd inetd_test.conf

$ telnet localhost 2121
bin
etc
...

Its work.
