Re: [uml-user] Detecting UML within UML

[- K. <k0...@ho...>]

Dear all.

Sorry, I got to ask again.

I put the detection in the beginning of rc.S (First initialisation).
Both methods do not work since /proc does not exist.

---------------
echoc "==> rc.S  Setting up the base system configuration....." blue
#sleep 2

# Checking the System
echoc "Detecting environment ..." red
CPU_MODEL=`cat /proc/cpuinfo | grep "model name" | cut -f2 -d : | cut -b 2-`
echo "Model : $CPU_MODEL"
# Failed because /proc does not exist

......
# Should be used here, but not working
# Check the root filesystem:
if [ ! $READWRITE = yes ]; then
  ## skip fsck if UML
  if [ ! "$CPU_MODEL" = "UML" ]; then
     echo "Checking filesystem for previous failures..."
     /sbin/fsck -A -C -a
     # If there was a failure, drop into single-user mode.
     if [ $? -gt 1 ] ; then
......
----------

Thanks in advance for any help.
