There's really no reason to use 10s here, let's instead default to 90s like we do for everything else. The SIGKILL during the final killing spree is in most regards the fourth level of a safety net, after all: any normal service should have already been stopped during the normal service shutdown logic, first via SIGTERM and then SIGKILL, and then also via SIGTERM during the finall killing spree before we send SIGKILL. And as a fourth level safety net it should only be required in exceptional cases, which means it's safe to rais the default timeout, as normal shutdowns should never be delayed by it. Note that journald excludes itself from the normal service shutdown, and relies on the final killing spree to terminate it (this is because it wants to cover the normal shutdown phase's complete logging). If the system's IO is excessively slow, then the 10s might not be enough for journald to sync everything to disk and logs might get lost during shutdown.
