Mounting encrypted drives

WSL can mount encrypted drives, but they must be mounted at the time wsl or bash runs the first time after boot.
If you do not execute any tasks when the host boots up, then just make sure your encrypted drives are mounted when you run wsl or bash.

If you do execute WSL tasks when the host boots up, replace the Task Scheduler entry for the trigger and make it rund after the Mount script has executed:

<QueryList>
  <Query Id="0" Path="Microsoft-Windows-TaskScheduler/Operational">
    <Select Path="Microsoft-Windows-TaskScheduler/Operational">*[EventData[@Name='TaskSuccessEvent'][Data[@Name='TaskName']='\Mount']]</Select>
  </Query>
</QueryList>

Remember to “Enable All Task History” under Actions tab. You might need to do this again after a Windows 10 major version upgrade.

Mounting external drives

mkdir /mnt/f
mount -t drvfs f: /mnt/f
