This change will only affect you if you write or use programs
or scripts that parse the syslog file.
The format of text messages logged in the syslog file by the su and login commands has changed slightly. Specifically, su events
are now preceded by ‘su:’ and login events are now
preceded by ‘login:’. As a result, syslog output
is now more consistent with the format of messages generated by
other commands. It is also easier for programs to operate that parse
syslog output.
Aside from affecting the text logged in the syslog file, this
change may possibly impact any programs that parse the syslog file,
such as certain security monitoring tools.
Programs that read syslog files looking for su and login events
will need to take this change into account.
