allows entries with a FIFO as log destination in /etc/syslog.conf

Hello,

sysklogd accepts something like "kern.info |/var/log/kernel-info", where /var/log/kernel-info is a pre-created FIFO. The syslogd man page says:

  This  version  of  syslogd has support for logging output to named pipes
  (fifos).  A fifo or named pipe can be used as a destination for log messages
  by  prepending  a pipy  symbol  (``|'')  to  the name of the file.  This is
  handy for debugging.  Note that the fifo must be created with the mkfifo
  command before syslogd is started.

I attached a small patch (applies to busybox 1.20.2) which modifies syslogd.c to handle such targets, too.


Regards,

Christoph Schulz
