 * SailfishOS:Chum GUI Installer creates a persistent log file `/var/log/sailfishos-chum-gui-installer.log.txt`.
 * SailfishOS:Chum GUI Installer runs "unattended": I.e., without any manual steps, after its installation has been triggered, until the SailfishOS:Chum GUI application is installed.
-* SailfishOS:Chum GUI Installer is slow, because it calls `pkcon` three times, which acts quite slowly.  The minimal run time for SailfishOS:Chum GUI Installer is about 7 seconds, the typical run time is rather 10 seconds (measured from the moment SailfishOS:Chum GUI Installer's installation is triggered, until the SailfishOS:Chum GUI application is installed and its icon is displayed at the "launcher").  This is already a lot, but I rarely experienced a stalled Packagekit daemon (`packagekitd`, for which `pkcon` is just a command line frontend, communicating with the daemon via D-Bus) during heavy testing, which can be observed with the crude `pkmon` utility (`Ctrl-C` gets you out.:smiley:), so the SailfishOS:Chum GUI Installer tries to detect these "hangs" and to counter them: If that happens, its run time can be up to slightly more than 1 minute.  In the worst case a stalled PackageKit daemon (and with it its `pkcon` client process(es)) stalls SailfishOS:Chum GUI Installer, until the PackageKit daemon reaches its idle time out of 300 seconds (5 minutes; this could theoretically happen three times, resulting in a likely unsuccessful run time of more than 15 minutes).

+Also note that SailfishOS sometimes fails to show an icon of a freshly installed app on the launcher ("homescreen") until SailfishOS is rebooted (rsp. more precisely: Lipstick is restarted).
