Building fully offline
-----------------------
For building fully offline including attaching signatures to unsigned builds, the detached-sigs repository
and the bitcoin git repository with the desired tag must both be available locally, and then gbuild must be
told where to find them. It also requires an apt-cacher-ng which is fully-populated but set to offline mode, or
manually disabling gitian-builder's use of apt-get to update the VM build environment.
To configure apt-cacher-ng as an offline cacher, you will need to first populate its cache with the relevant
files. You must additionally patch target-bin/bootstrap-fixup to set its apt sources to something other than
plain archive.ubuntu.com: us.archive.ubuntu.com works.
So, if you use LXC:
```bash
export PATH="$PATH":/path/to/gitian-builder/libexec
export USE_LXC=1
cd /path/to/gitian-builder
./libexec/make-clean-vm --suite precise --arch amd64
LXC_ARCH=amd64 LXC_SUITE=precise on-target -u root apt-get update
LXC_ARCH=amd64 LXC_SUITE=precise on-target -u root \
-e DEBIAN_FRONTEND=noninteractive apt-get --no-install-recommends -y install \
$( sed -ne '/^packages:/,/[^-] .*/ {/^- .*/{s/"//g;s/- //;p}}' ../bitcoin/contrib/gitian-descriptors/*|sort|uniq )
LXC_ARCH=amd64 LXC_SUITE=precise on-target -u root apt-get -q -y purge grub
LXC_ARCH=amd64 LXC_SUITE=precise on-target -u root -e DEBIAN_FRONTEND=noninteractive apt-get -y dist-upgrade
```
And then set offline mode for apt-cacher-ng:
```
/etc/apt-cacher-ng/acng.conf
[...]
Offlinemode: 1
[...]
service apt-cacher-ng restart
```
Then when building, override the remote URLs that gbuild would otherwise pull from the gitian descriptors::
```bash
cd /some/root/path/
git clone https://github.com/bitcoin/bitcoin-detached-sigs.git
BTCPATH=/some/root/path/bitcoin.git
SIGPATH=/some/root/path/bitcoin-detached-sigs.git
./bin/gbuild --url bitcoin=${BTCPATH},signature=${SIGPATH} ../bitcoin/contrib/gitian-descriptors/gitian-win-signer.yml
```

pushd ./bitcoin
git checkout v${VERSION}

NOTE: Offline builds must use the --url flag to ensure gitian fetches only from local URLs.
For example: ./bin/bguild --url bitcoin=/path/to/bitcoin,signature=/path/to/sigs {rest of arguments}
The following gbuild invocations DO NOT DO THIS by default.
