# halo-os
## Intro
This is a prototype outline for building and deploying a debian based OS with
ostree. For purposes of demonstration, the OS runs from a bootable USB device
on a UEFI capable amd64 machine. Once a USB device is created and booted, the
OS can be updated using a simple shell script.
## Obtaining prebuilt usb images
Prebuilt usb device images are available here: <https://os.halo.nu/images/>
A gpg signed checksum file is available to verify authenticity.
Download the `.img.gz` and the `.img.bmap` file locally and use bmaptool to
write to a usb device. e.g:
sudo bmaptool copy ./halo-01-usb-*.img /dev/sdX
## Using the running system
On first boot, the system should re-partition the usb device and grow the root
filesystem for you.
### Login
Login as `trent` with the password `reznor`
### Connect to the internet
Use network manager on the cli to connect to the internet
nmtui
### Update
Check for and apply system updates from public ostree repo, hosted at
<https://os.halo.nu/repo-dev/>:
# halo-upgrade
## Building locally
$ sudo ./build-os # build the os in a chroot, tweak it for ostree
$ sudo ./commit-os # commit the root filesystem to an ostree build repo
$ ./publish-repo # migrate the content to an archive repo
$ sudo ./generate-usb-img # build a bootable usb image file
$ ./sync-repo # sync the archive repo up to a webserver
