## `blocklist`
|
|
|
|
Hosts that I dislike enough to mention in my `hosts` file.
|
|
|
|
## `dns`
|
|
|
|
This began from question why should I have DNS to have DNS, but having it on
|
|
DNS resolver level broke DNSSEC due to my weird mixing of systemd-resolved and
|
|
Unbound, so now it's something I can attempt to `/etc/hosts`.
|
|
|
|
**_EXCERCISE CAUTION!_**
|
|
|
|
## `hostname`
|
|
|
|
As can be seen in `hosts.debian`, Debian specifies hostname in format such as:
|
|
|
|
```
|
|
::1 localhost
|
|
::1 FQDN UQDN
|
|
|
|
127.0.0.1 localhost
|
|
127.0.1.1 FQDN UQDN
|
|
```
|
|
|
|
where FQDN means _Fully Qualified Domain Name_ and UQDN _Unqualified Domain
|
|
Name_ (although I don't know if anyone else calls it like that) and I find
|
|
that a good practice. Additionally I have observed my systems querying their
|
|
own hostname from global DNS which seems unnecessary and not a great behaviour
|
|
to me, while this file appended to `/etc/hosts` can tell it immediately all
|
|
applications and make `resolvectl query hostname.localdomain` find it
|
|
instantly.
|
|
|
|
The `0200:0000:0000:0000:0000:0000:0000:0000`? Replace it with your Yggdrasil
|
|
address from `yggdrasilctl getself`.
|
|
|
|
## `hosts.arch`
|
|
|
|
For now this is a symlink to `hosts.steamos` as I am pretty sure they haven't
|
|
modified it.
|
|
|
|
## `hosts.fedora`
|
|
|
|
I am pretty sure this is the `/etc/hosts` that was given me by Fedora < 40
|
|
with changes removed.
|
|
|
|
## `hosts.debian`
|
|
|
|
I think this is the Debian format which used to be just `../hosts` in this
|
|
repository.
|
|
|
|
## `hosts.steamos`
|
|
|
|
The `/etc/hosts` file from `SteamOS Holo` variant steamdeck version `3.5.19`
|
|
or `20240422.1`.
