Installation

Instructions for more CDN:

Update system via apt
- Software: vim, rsync, ufw (default IPv4, 22/tcp, 68/udp, 445/tcp, 53), htop, curl, git
Add /usr/sbin to PATH
Add apt-cacher-ng and auto-apt-proxy
Install uv
Install sudo, set root password and enable use of root password for sudo authentication
Create Samba directory
Configuration:
- /etc/bash.bashrc
- /etc/inputrc
- /etc/vim/vimrc.local
- /usr/share/vim/vim90
- /etc/unbound/unbound.conf
DNS:
- No resolveconf program seems to be provided, and the initial resolv.conf is set by dhclient from DNS.
- According to Debian wiki, either openresolv or resolvconf should be installed and used. Openresolv seems to be the way forward.
- According to Bookworm release notes, systemd-resolved was never the default resolver on Debian.
- Hand modify /etc/resolv.conf
  - For Ubuntu, we modify /etc/systemd/resolved.conf instead

user:~$ sudo apt install openresolv
user:~$ sudo vim /etc/resolvconf.conf
name_servers=127.0.0.1
# Prevent override by other daemons
resolvconf=NO
