alias 'su' to 'su -' so that they cannot so mess up?

depending on the shell, there is also the ability to have an 
'on exit' script fire and harvest the 'depends on the shell' 
history file, if any

also there are logging shells, a la script, but less avoidable

finally, I have a copy of the sources from the last GPL 
released version of such a logging environment at:
 	ftp://ftp.owlriver.com/pub/mirror/ORC/eas/

touted as an: Enterprise Audit Shell

'Enterprise Audit Shell enables organizations to centrally 
control and audit UNIX shell access. Audit logs are recorded 
and archived detailing shell input and output, which can be 
played back and reviewed'

the FOSS project underlying such was bought, and the sources 
taken down promptly right after the 2.0 version was released, 
but my mirroring strategies permitted me to look back in time 
to snag it
