The syntax from using the private-key field is more convenient than writing a
custom PreUp command (more formatting and preshared keys). Instead of trying
to guess if private-key is/is not a file path, add an option to disable
bootstrapping while still using private-key.
* gnu/services/vpn.scm (<wireguard-configuration>): Add
bootstrap-private-key?.
(wireguard-activation): Check bootstrap-private-key? before bootstrapping.
* doc/guix.texi (VPN Services)[wireguard]: Document it.

+@item @code{bootstrap-private-key?} (default: @code{#t})
+Whether or not the private key should be generated automatically if it
+does not exist.
+
+Setting this to @code{#f} allows one to set the private key using
+command substitution. One example shown in the @code{wg-quick(8)}
+manual is retrieving a private key using @code{password-store}. This
+can be achieved with the following code:
+
+@lisp
+(wireguard-configuration
+ (private-key
+ #~(string-append "<("
+ #$(file-append password-store "/bin/pass")
+ ;; Wireguard replaces %i with the interface name.
+ " WireGuard/private-keys/%i)")))
+@end lisp
+
+
@item @code{peers} (default: @code{'()})
The authorized peers on this interface. This is a list of
@var{wireguard-peer} records.
