Issue description

In the RH104 lab titled "Lab: Working with a Linux System", the exercise compreview-review2 fails grading with the message:

FAIL Validating the contents of the sysinfo.txt file on servera
FAIL Validating the contents of the sysinfo.txt file on workstation, 

even when it follows the instructions exactly as provided.

Steps to reproduce:

The course content instructs learners to build sysinfo.txt manually using echo and specific values:

echo "IP: 172.25.250.10/24" >> sysinfo.txt
echo "Disk: 9.4GB" >> sysinfo.txt
echo "Memory: 1770MB" >> sysinfo.txt
echo "Timezone: EST" >> sysinfo.txt

However, the grading script performs a strict binary comparison using:

cmp /tmp/.grading/sysinfo.txt /home/student/sysinfo.txt

The /tmp/.grading/sysinfo.txt is auto-generated by the script using system commands:

hostname
ip -br -4 addr show dev eth0 | awk '{ print $3 }'
df -h --output=size / | grep -v Size
free -m | awk '/Mem:/ { print $2 }'
date +%Z

Therefore, any deviation such as:

spacing differences (e.g. 9.4 GB vs 9.4GB)

memory format (e.g. 1770MB vs 1770 MB)

missing MB/GB units

trailing newline characters

omission of /24 in CIDR

will result in a false negative grading outcome.

Please review, thank you
