It is still under construction and content may change. Do not rely on this information.
Contents
Intro
OPS235 is due for another update, to Fedora 16 + current practices. This page is a scratchpad for recording proposed changes.
Course Structure
Brian has proposed a number of changes to the course structure. Unfortunately, at the time of writing, Mercury is down so I can't check them, but IIRC:
Tests
Drop written test #2.
Assignments
Use one larger assignment.
Labs
Drop lab #1.
Course Content
Anaconda Changes
The Anaconda UI has changed, especially for storage configuration.
SysVInit -> Systemd
Systemd has replaced the sysvinit system. Since systemd has been accepted by other distros, we should teach it as the primary init system. However, we should touch on the POSIX/sysvinit tools as well because they're still common in the wild.
- Add:
- systemctl
- unit files
- service levels
- Reduce:
- chkconfig
- service
- Discuss:
- Bind mounts (ugly mount table)
ext4
Use ext4 as the standard filesystem. Add some discussion of btrfs.
Interface Names
Interfaces are now named according to BIOS/EFI device labels. This is important for server-class systems which are rackmounted. In the past, "eth0", "eth1", "eth2" were hard to line up with back-panel connectors; now, if the BIOS/EFI says that the ports are labelled "network-A", "network-B", and "network-C", that's what the interface names are. If there are no names in the BIOS/EFI, embedded ports come up as emX and PCI ports come up as pXpN (PCI slot X port N).
Loopback Mount Option
No longer required -- loopback is assumed if the mount source is not a block device.
netstat
Command is obsolete according to the documentation. Change coverage to the 'ip' command.
git
Add coverage of the git version-control system.
Course Page Layout
Refactor Web Pages
Students are doing the labs without, in some cases, really understanding what they're supposed to be understanding from the lab. Proposed structure:
- Challenge - outline the task that needs to be performed
- Background - background information for the task
- Resources - links to resources related to the task
- Before You Begin - preparation and warnings before starting
- Steps - how to perform the task
- Debugging - debugging guidelines for this type of task (e.g., for network connectivity issues, guide through "IP, routing, nameservice" debugging)
- Observations - things which the student should note or think through
- Submitting the Lab - how to get the lab marked -- Question: Should this be based more on the Observations and less on the Steps section above?
- Preparing for the Quizzes - additional questions to be answered
Use graphics more extensively
- Create some templates for graphics for sections and notes
- Break the page up visually so that it's not one massive bunch'o'scrolling
