fix: use x-platform code for pdeathsig

This might cause the macosx build not to fail, I hope.

-`abra` is a command-line tool for managing your own [Co-op Cloud](https://coopcloud.tech). It can provision new servers, create applications, deploy them, run backup and restore operations and a whole lot of other things. It is the go-to tool for day-to-day operations when managing a Co-op Cloud instance.

-## Install
-
-### Arch-based Linux Distros
-
-[abra (coming-soon)](https://aur.archlinux.org/packages/abra/) or for the latest version on git [abra-git](https://aur.archlinux.org/packages/abra-git/)

-### Build from source
-
-```sh
-git clone https://git.coopcloud.tech/coop-cloud/abra
-cd abra
-go env -w GOPRIVATE=coopcloud.tech
-make install
-```
-
-The abra binary will be in `$GOPATH/bin`.
-
-## Autocompletion
-
-**bash**
-
-Copy `scripts/autocomplete/bash` into `/etc/bash_completion.d/` and rename
-it to abra.
-
-```
-sudo cp scripts/autocomplete/bash /etc/bash_completion.d/abra
-source /etc/bash_completion.d/abra
-```
-
-**(fi)zsh**
-
-(fi)zsh doesn't have an autocompletion folder by default but you can create one, then copy `scripts/autocomplete/zsh` into it and add a couple lines to your `~/.zshrc` or `~/.fizsh/.fizshrc`
-
-```
-sudo mkdir /etc/zsh/completion.d/
-sudo cp scripts/autocomplete/zsh /etc/zsh/completion.d/abra
-echo "PROG=abra\n_CLI_ZSH_AUTOCOMPLETE_HACK=1\nsource /etc/zsh/completion.d/abra" >> ~/.zshrc
-```
-
-(replace .zshrc with ~/.fizsh/.fizshrc if you use fizsh)
 
 ## Hacking
 
-Install direnv, run `cp .envrc.sample .envrc`, then run `direnv allow` in this directory. This will set coopcloud repos as private due to [this bug.](https://git.coopcloud.tech/coop-cloud/coopcloud.tech/issues/20#issuecomment-8201). Or you can run `go env -w GOPRIVATE=coopcloud.tech` but I'm not sure how persistent this is.
+### Getting started
+
+Install [direnv](https://direnv.net), run `cp .envrc.sample .envrc`, then run `direnv allow` in this directory. This will set coopcloud repos as private due to [this bug.](https://git.coopcloud.tech/coop-cloud/coopcloud.tech/issues/20#issuecomment-8201). Or you can run `go env -w GOPRIVATE=coopcloud.tech` but I'm not sure how persistent this is.
 
 Install [Go >= 1.16](https://golang.org/doc/install) and then:
 
 - `make build` to build
 - `./abra` to run commands
 - `make test` will run tests
+- `make install` will install it to `$GOPATH/bin`
+- `go get <package>` and `go mod tidy` to add a new dependency
 
 Our [Drone CI configuration](.drone.yml) runs a number of sanity on each pushed commit. See the [Makefile](./Makefile) for more handy targets.
 
 Please use the [conventional commit format](https://www.conventionalcommits.org/en/v1.0.0/) for your commits so we can automate our change log.
 
-## Versioning
+### Versioning
 
 We use [goreleaser](https://goreleaser.com) to help us automate releases. We use [semver](https://semver.org) for versioning all releases of the tool. While we are still in the public alpha release phase, we will maintain a `0.y.z-alpha` format. Change logs are generated from our commit logs. We are still working this out and aim to refine our release praxis as we go.
 
 For developers, while using this `-alpha` format, the `y` part is the "major" version part. So, if you make breaking changes, you increment that and _not_ the `x` part. So, if you're on `0.1.0-alpha`, then you'd go to `0.1.1-alpha` for a backwards compatible change and `0.2.0-alpha` for a backwards incompatible change.
 
-## Making a new release
+### Making a new release
 
 - Change `ABRA_VERSION` to match the new tag in [`scripts`](./scripts/installer/installer) (use [semver](https://semver.org))
-- Commit that change (e.g. `git commit -m 'chore: publish next tag 0.3.1-alpha'`)
+- Commit that change (e.g. `git commit -m 'chore: publish next tag x.y.z-alpha'`)
-- Make a new tag (e.g. `git tag 0.y.z-alpha`)
+- Make a new tag (e.g. `git tag -a x.y.z-alpha`)
 - Push the new tag (e.g. `git push && git push --tags`)
 - Wait until the build finishes on [build.coopcloud.tech](https://build.coopcloud.tech/coop-cloud/abra)
 - Deploy the new installer script (e.g. `cd ./scripts/installer && make`)
-- Check the release worked, (e.g. `abra upgrade; abra version`)
+- Check the release worked, (e.g. `abra upgrade; abra -v`)

-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,

-      of your accepting any such warranty or additional liability.

-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
