Denton Gentry 280c84e46a ipn/ipnserver, paths, logpolicy: move Window config files out of %LocalAppData% ... C:\WINDOWS\system32\config\systemprofile\AppData\Local\ is frequently cleared for almost any reason: Windows updates, System Restore, even various System Cleaner utilities. The server-state.conf file in AppData\Local could be deleted at any time, which would break login until the node is removed from the Admin Panel allowing it to create a new key. Carefully copy any AppData state to ProgramData at startup. If copying the state fails, continue to use AppData so at least there will be connectivity. If there is no state, use ProgramData. We also migrate the log.conf file. Very old versions of Tailscale named the EXE tailscale-ipn, so the log conf was tailscale-ipn.log.conf and more recent versions preserved this filename and cmdName in logs. In this migration we always update the filename to c:\ProgramData\Tailscale\tailscaled.log.conf Updates https://github.com/tailscale/tailscale/issues/2856 Signed-off-by: Denton Gentry <dgentry@tailscale.com>		2021-09-19 22:57:53 -07:00
