Reinstalling Sanity

====== WSL 2 ======

As of 13.8.21, WSL 2 is also available, with a currently more complicated install: https://docs.microsoft.com/en-us/windows/wsl/install-win10

WSL 2 uses a virtual machine in order to run the actual Linux kernel, this is meant to improve performance across the board.  Probably best to use this.

Resolve issues: as of Aug 2021 the WSL machine can connect to external IPs but not resolve names.

Check out /etc/resolv.conf -- you can disable autoupdating, then remove it (it's a symlink) and replace it with something sane (''nameserver 8.8.8.8'' for a start).

But that may not help.  This did: https://gist.github.com/sivinnguyen/8bc0125b274250683a97e149cf270040 but it nuked my Windows network settings, which can be reapplied from ''run'' -> ''ncpa.cpl''.  For some reason the new Win 10 network settings couldn't change the IP address.

Install Windows Terminal from the Windows Store.  Hopefully you have saved a profile at some point or can export it(''settings.json'').
====== WSL 1 ======

  * Control Panel > Programs and Features > Turn Windows Features On Or Off
    * Enable "Windows Subsystem for Linux"
  * Restart
  * Microsoft store > search for "Debian" > Get (need to disconnect VPN or create an account)
  * Launch from the start menu

The directory ''/var/run/screen/'' is the socket directory for screen.

Fortunately, screen reads a environment variable ''SCREENDIR'' to get an alternative socket directory.

So to work around it, you can create a directory, such as ''~/.screen'':

''mkdir ~/.screen && chmod 700 ~/.screen''

and export the ''SCREENDIR'' to point to that directory:

''export SCREENDIR=$HOME/.screen''

You can also put this line into your ''~/.bashrc'' so that it will also take effect afterwards.


====== Samba ======

You can't automatically access Windows network drives, even if they are mapped to a letter (20.6.20).

''/etc/fstab'':

    \\alan\huge  /mnt/y  drvfs  user,uid=1000,gid=1000  0  0

This ought to automount when WSL is fired up, but something[TM] needs to start it if you want to run ''rsync'' from ''cron''.

====== cron ======

Add to the end of ''/etc/sudoers'':

    %sudo   ALL=NOPASSWD: /etc/init.d/cron start

Roughly, follow https://blog.snowme34.com/post/schedule-tasks-using-crontab-on-windows-10-with-wsl/index.html although I think there was a lot of fighting to create the link:

    Next, type shell:startup in the Run and explorer will open the startup folder.

    Create a shortcut to wsl.exe and edit the properties as following:

    C:\Windows\System32\wsl.exe sudo /etc/init.d/cron start
