Hey Andy,

As you know, I've been playing with the rsylog branch[1] by adding some
live logging of the installation. However, I may have hit a bump in the
road when testing server images. The server install runs from a busybox
shell which includes a simplified "logger" implementation that doesn't
seem to work with rsyslog.
I'm curious to know what doesn't work exactly with remote syslog and
debian-installer based installation (server images)? I haven't found a
single bug in Debian and Ubuntu about remote logging not working during
installation.
I don't know all the permutations of installers we have to support, but
I'm starting to wonder if assuming an installer will have a properly
functioning rsylog'er is feasible?
This issue coupled with the fact I haven't been that excited about
dealing with rsyslogd (it seems like it can finicky at times). Has me
wondering: Do we need something different.
Since I'm new, you might be able to stop me here with a "don't worry".
If I'm not crazy, then its time to talk solutions. I'll pitch an idea
and see what you think:
We make 3 assumptions:
1) target has network
2) target supports "tail -f"
3) target includes netcat "nc".
With those assumptions you could basically spawn something like:
tail -f /var/log/syslog | nc <host> <port>
That won't work on ubiquity based installations because of LP #882147 (
overlayfs does not implement inotify interfaces correctly) You'll have
to use busybox tail instead which uses polling instead of inotify.
somewhere early in the install (I think there's some type of preseed
support for this).
Then you create some minmial twisted lineReceiver service when UTAH is
run that listens on an ephemeral port and processes these messages from
the target.
thoughts?
I think you should first figure why a standard remote logging facility
like rsyslog doesn't work before adding more complexity (and as a
consequence more development time, more maintenance and less
reliability) to UTAH.
