## wsl.conf
[boot]
    command="printf \"nameserver 1.1.1.1\n$(cat /etc/resolv.conf)\nnameserver 8.8.8.8\nnameserver 1.0.0.1\n\" > /etc/resolv.conf"

# Where does this go?
#   In each WSL2 distribution, add this to your `/etc/wsl.conf` file.
#
# What this does:
# Writes 3 nameservers to your WSL2 distribution, and inserts the dynamic nameserver (the WSL2 -> Windows bridge) from
#   /etc/resolv.conf at level 2, and re-writes all that to the same /etc/resolv.conf file.
#
# 1. A subprocess reads the contents of the newly created file at boot, which has the bridge IP in it
#       by default. `$(cat /etc/resolv.conf)`
# 2. The `printf` command injects the result of that after the first nameserver, and before the other two (configure as needed)
# 3. The value to print is surrounded with double quotes, so that variable substitution can happen.
#       These are already in double quotes due to `command = "<full command>"`, so they are escaped: `\"`
# 4. The results of what is printed are written back to `/etc/resolv.conf`.
#
# Why?
# I had several issues with DNS inside the Linux distribution (several Ubuntu versions). For example,
#   terraform provider lookup failed after a few tries and it only tries twice (thus I put the public nameserver
#   before the Windows bridge).
# I don't remember where I saw that specific number of DNS attempts, but Possible Cause #3 at this link seems to be the reason.
