Indeed, it is not effective in the chroot.

One way to set this setting in the chroot is to pass an option
explicitly when running `lb config` (patch attached). Another way would
be to add a file into the `config` directory, but I'm not sure exactly
which file. According to today's live-build doc, creating a file
`config/apt/apt.conf` should work. But it doesn't seem to match the
existing layout, Tails already has a directory `config/chroot_apt`,
maybe it's better to drop a file there, however I didn't try.

Anyway.

The fact is that it doesn't help me much, because apt-get **will not**
retry when it's run along `apt-cacher-ng`. I strongly suspect that it's
because apt-cacher-ng returns an error code 503 "Service Unavailable" on
failure, instead of forwarding the original error code. I got in touch
with apt-cacher-ng and let you know when I know more about that.

Cheers
