Answer the Investigation 8 question in your lab logbook.
===Investigation 9 - How do you create a file system in a regular file?===
# Create an empty file that is exactly 3 MB in size using the following command:
#* <code>dd if=/dev/zero of=/tmp/fstest bs=1k count=3072</code>
# How does this command ensure that the file is 3 MB in size?
# What is in the file at first?
# Create an ext3 filesystem within the newly-created file <code>/tmp/fstest</code>.
# Note the warning message/question that appears.
# Mount the filesystem (remember to use the loopback option; refer to Investigation 8 if required). Use a mountpoint of your choosing.
# Copy the files <code>/etc/services</code> and <code>/etc/protocols</code> to the filesystem mounted in the previous step.
# Unmount the filesystem.
# Test your filesystem to be sure that the files <code>/etc/services</code> and <code>/etc/protocols</code> were in fact copied into the filesystem within the file named <code>/tmp/fstest</code>.
# How much space is left in that filesystem? (Hint: <code>df -h</code>).
