Fwd: [utah-devel] New Stable Version

[Dmitrijs Ledkovs]

Below is partial thread from utah-devel mentioning using remote
syslogging with ubiquity.
Looks like checkbox satellite & now utah (for autopilot bare metal
jobs) both want rsyslogd.
I wonder if we can integrate rsyslogd into the images, without
requiring manual repacking steps.

Regards,

Dmitrijs.

Hi,

I spoke to Max a few days ago about this, and I forgot to mention (sorry!) that
while d-i knows about remote syslogging which works out of the box,
ubiquity/casper do not; therefore, to get this working with checkbox-satellite
we had to make a tiny modification to the initrd file, to properly configure
casper's syslog to log remotely. This is compatible with the kernel paramater
syntax described above.

1- Unpack the initrd.lz
2- Add a couple of lines need to added to scripts/init-bottom/ORDER, and a small
script needs to be copied to scripts/init-bottom
3- repack the initrd.lz
4- use that initrd.lz to boot the system, it should automagically pick up
log_host and log_port.

These modifications are described in lp:checkbox-satellite, look in initrd/lz,
the "patch" file is a script that automatically does step 2 above, and the
'rsyslog' is the script that needs to be dropped in scripts/init-bottom.

There's also a scripts/initrd_patch script, which takes care of applying these
patches to initrd. It's used like this:

scripts/initrd_patch <path_to_initrd.lz> <path_to_rsyslog.patch>

These scripts are pretty much independent from the rest of checkbox_satellite.
You can potentially just take initrd_patch, rsyslog.patch and rsyslog, and put
them somewhere in utah where they make sense.

Let me know if I can help further with this.

Cheers!
- Daniel
