Hi Maxim and Ludo’, I hacked profiles.scm (please see git diff below) so that start and end seconds appear in the message like this: creating manual page database for 23 packages...1494773268...1494773275 DONE I tested a few cases and man-db typically takes only a few seconds. It only _appears_ to take a long time because other processing occurs after the man-db command. So, I suggest either ... 1) delete the message altogether, or 2) close the message with a "DONE" SORRY for the run-around. In my defense, when I first raised the question I did suggest the idea of closing the message: http://lists.gnu.org/archive/html/guix-devel/2017-04/msg00196.html HTH, George g1@g1 ~/src/guix [env]$ git diff diff --git a/guix/profiles.scm b/guix/profiles.scm index eb172ef45..4dbf44a81 100644 --- a/guix/profiles.scm +++ b/guix/profiles.scm @@ -1011,13 +1011,15 @@ the entries in MANIFEST."
