Can I safely upgrade SA from 3.4.0 to 3.4.1 without changing any local

yes, but you need to run "sa-update" before restart to fetch the
latest rules and hopefully have a distribution which restarts
automatically after update the package

Isn't this a contradiction?  If my distribution automatically restarts
(which it does), how can I sneak in a sa-update run after the upgrade
but before the restart?

i hope you have a testing environment for production and so just make
the "sa-update" there and rsync the rule-updates to the liveserver

I appreciate you trying to help, but you don't really answer my
question.  Even if I could do what you suggest, the rsync would still
take finite time - longer than the interval between the upgrade and the
restart on the production system.

no, you don't need to change anything else

in most setups regenerate bayes would even be impossible because you don't have the autolearned messages to do so if you have your whole corpus (like we do) you should rebuild the bayes again from the samples - especially if you are using "normalize_charset 1" and possibly to make "bayes_token_sources all" if you chose to use it also benefit from the older samples but there is no need to do so, the old bayes don't become useles
