1. Werner's suggestion for re-instating syslog in Knoppix 7's must
be applied before adding any overlays.

2. The Knoppix 7.2 .bashrc function indicated in my post #9 will not
work as is without modification in Knoppix 7.4. Adaptations which will
work are as follows:
Code:
# Excerpts from my Knoppix 7.4 .bashrc:

alias 'Syslog=sudo less /var/log/syslog'  # requires syslog

at.Start(){ # echo time at Start (requires Syslog)
echo -e "at Start:   \c"; Syslog | grep 'acpid: start' | awk '{ print $3 }'
}

Disconnects() { # Wifi disconnects since boot (requires Syslog)
echo -e "Time now:   \c"; date | awk '{ print $4 }' 
at.Start
echo -e "Wifi disconnects:  \c"; Syslog | grep -c disconnecting
}
3. It may not be possible to estimate time to boot using syslog in
Knoppix 7.4.

4. Thanks again go to Werner for pointing out there are pitfalls in
using Knoppix's overlay process which must be observed.
