The /etc/login.defs file as shipped in login today has this set to "yes". Having login and su behave differently does not appear to be an option today, so I don't think "no" for this setting is actually important? > > SULOG_FILE > > It seems shadow had the intention for *optional* support of syslog (but > it's actually always enabled at compile-time and configurable at > runtime), and non-optional support for built-in logging system.

Dropping the second one sure sounds safe, but the first one looks like it changes commonly used behaviour? How does su from util-linux handle that?
