**What's done** - using `setcap` in Linux to be able to bind ports - for install - for update - changed the Heath command to say whether the capability is set or not --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

There's no such cli tool like `security` on Ubuntu, so everything is
mostly manual.
**Where do certs live in Linux**
Certs live in `/etc/ssl/certs`, but this directory is mostly a
collection of symlinks that shouldn't be updated directly.
Instead, we copy our cert to `/usr/local/share/ca-certificates` and then
run `update-ca-certificates` to update the symlinks.
**Where do Firefox certs live in Linux**
Depends!
I found three places depending on how Firefox was installed and what
your Linux is.
```
let profile_dirs = [
".mozilla/firefox",
"snap/firefox/common/.mozilla/firefox",
".var/app/org.mozilla.firefox/.mozilla/firefox",
];
```
**How to test**
- pull the branch on a Ubuntu machine
- `cd linkup-cli && cargo install --path .`
- `cd ..` — get back to the root of the repo
- `sudo setcap cap_net_bind_service=+ep ~/.cargo/bin/linkup`
- `export LINKUP_CONFIG=~/linkup/linkup-config.yaml`
- `export PATH=$PATH:~/.cargo/bin/linkup >> ~/.bashrc`
- `source ~/.bashrc`
- `linkup start`
- `linkup local-dns install`
- `linkup health`

…ns (#236) macOS doesn’t expose each thread as a “full” process. However, Linux does. Which results in lots of thread-duplicates on `linkup health` on Linux. [From the Apple documentation](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Multithreading/CreatingThreads/CreatingThreads.html?utm_source=chatgpt.com) > Each process (application) in OS X or iOS is made up of one or more threads, each of which represents a single path of execution through the application's code. Whereas in Linux, a thread is a process on its own.
- baggage headers will still be _forwarded_ -> linkup forwards headers by default - this header is currently not used - tracestate should continue to be the primary method of linkup state propogation - less things to think about - more simple

Linkup 3 stopped using remote certificate management. So the worker don't need to have this feature anymore. We are still missing the localdns feature on Linkup 3, but that is currently being fixed on #233. After that, we can consider merging and deploying this.
