add line to /etc/services

[Radovan Garabik <garabik@melkor.dnp.fmph.uniba.sk>]

I am packaging a program
(http://melkor.dnp.fmph.uniba.sk/~garabik/xtell.html)
which is a daemon, and can run from inetd. As such, it needs
an entry in /etc/services. What is the best way to add a line
to the file? Currently I am using 

update-inetd --file /etc/services --add 'xtell  4224/tcp # xtell server'
update-inetd --add 'xtell  stream  tcp  nowait  nobody /usr/sbin/tcpd  /usr/sbin/xtelld'

but I feel a bit uneasy about it. (update-inetd was not designed to do this, 
/etc/services is a conffile of netbase, and can be overwritten when netbase 
is upgraded etc...)

thanks for suggestions
