Introduction
There are two techniques used to place multiple files within one file: the first is to create a filesystem within a file, and the second is to use an archive program to create an archive file. Archive files are often used to contain source code for software; in this lab you will also be compiling software from a source code archive. Finally, you will modify your system startup to eliminate unnecessary services and configure your system to automatically mount a partition.
Investigation 1: How do you create and use a filesystem in a regular file?
Use fedora3
Perform these steps in the fedora3 virtual machine.
Perform these steps in the fedora3 virtual machine.
- Login using your Learn ID
- Create an empty file that is exactly 3 MB in size:
dd if=/dev/zero of=/tmp/fstest bs=1k count=3072
- 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
/tmp/fstest. Note the warning message/question that appears - Mount the filesystem (remember to use the loopback option; refer to Lab 1 if required). Use a mountpoint of your choosing.
- Copy the files
/etc/servicesand/etc/protocolsto the filesystem mounted in the previous step - Unmount the filesystem
- Test your filesystem to be sure that the files
/etc/servicesand/etc/protocolswere in fact copied into the filesystem within the file named/tmp/fstest. - How much space is left in that filesystem? (Hint:
df -h).
Make sure that your lab notes answer the Investigation 1 question.
