Subject: [PATCH 2/2] scripts: lint: Set the %link-checker-store-connection
 parameter.
Date: Thu, 26 Dec 2019 18:01:04 +0000

If set, this parameter provides a store connection used by the derivation
linter. Without this being set, the derivation linter establishes a new
connection for each package. With this change, I saw the time taken to lint
all packages with the derivation linter drop from over 4 minutes to around 3
minutes.

* guix/scripts/lint.scm (guix-lint): Set the %lint-checker-store-connection)
parameter.
