+====== 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

+  * Fix [[https://superuser.com/questions/1195962/cannot-make-directory-var-run-screen-permission-denied|screen]]:
+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
