[BusyBox] Redirect console to /dev/pts/0

[Matthias Fuchs]

Hi Brett,

can't you use the remote logging capabilities of the syslogd ? It should be possible
to send all syslog messages (incl. kernel messages) to a remote syslogd.

An other idea could be to use a modified syslogd as login shell for a telnetd that is running on a
special port.

Hope that helps.

Matthias

But the busybox system is an embedded one and so recompiling the kernel multiple times and recreating a compressed root image is a pain (and everyone tries to avoid pain).
