Under /etc/runit I found a file named "2" (number two, without quotes) and with the following content:
#!/bin/sh
PATH=/command:/usr/local/bin:/usr/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin
exec </dev/null
exec runsvdir -P /service 'log: ..........................................
with more than 350 dots.
I can't remember anything similar, but found in two servers, so I think there is no hack or something.
