Comment 8 for bug 1013843

Hi Thomas,

The late_command (or ubiquity's success_command) is run after the rest of the installation has finished (I think it even runs after installing the boot loader), but the system doesn't reboot prior to running it.

I did the test you requested on a Precise system. Here's what I do (and also what I did on Quantal to produce the output on comment #3):

- Start the PXE installation process
- As the installation starts (e.g. the system says creating filesystem), I go to a virtual console
- From here, cat /etc/resolv.conf shows the file I posted in the original report (on Quantal) or a correctly-poopulated file (on Precise; I'll attach this below).
- I run the script you provided, using "script" to capture the output, e.g.
  script output.txt
  ./thomas-script.sh
- I put the output.txt file on a USB stick and shuttle back to my laptop :0

So as promised, here's the result of running all those commands on a Precise installation. I see resolv.conf has correct DNS information (as taken from DHCP) and I also notice it's a symlink:
