# the only non-interactive way to set up a WSL distro is the --root flag
#    https://github.com/microsoft/WSL/issues/3369
# but it has the side effect of making all `wsl` calls run as root,
# so users still need to manually intervene to set up a regular account.
# Workaround this by installing with --root but then replicating,
# noninteractively, what happens in the WSL DistroLauncher:

NOTE: Other distros can be scripted the same way for example:

#--- SLES ---
# Install SLES Store app
Invoke-WebRequest -Uri https://aka.ms/wsl-sles-12 -OutFile ~/SLES.appx -UseBasicParsing
Add-AppxPackage -Path ~/SLES.appx
# Launch SLES
sles-12.exe

# --- openSUSE ---
Invoke-WebRequest -Uri https://aka.ms/wsl-opensuse-42 -OutFile ~/openSUSE.appx -UseBasicParsing
Add-AppxPackage -Path ~/openSUSE.appx
# Launch openSUSE
opensuse-42.exe
