Once again, I've been involved in developing an LPI training course for
my client. In going over the objectives for the 101 exam, I've come
across quite a bit of outdated information. So, I'm wondering, do I
need to tell students about the following topics? Or, has the exam been
updated to reflect more updated information?
/proc/pci
This file no longer exists on new systems. The newest system I have
that still has it is a derivative of Red Hat Enterprise 4. RHEL 5,
Debian 4.0, and Ubuntu all use "/proc/bus/pci/devices", instead.
scsi_info
This utility hasn't been around for quite a while. It's been replaced
by "lsscsi" and the "sg3_utils" utilities.
usbmgr, /etc/usbmgr, and usbmodules
These are no longer used.
hotplug
This has been replaced by udev, and is no longer installed on any modern
Linux distro.
sndconfig and isapnp
Okay, these aren't in the exam objectives, but several other books that
are still in print talk about these. Since they only apply to ISA bus
devices, I would be very surprised if there's still anyone left who
would have use for them.
Also, there's the general topic of configuring devices so as to avoid
IRQ, ioports, and DMA conflicts. Now that most, if not all, ISA bus
devices have been replaced with PCI or PCIe bus devices, is there still
a need for this topic at all? PCI and PCIe devices get configured
dynamically, and there's really not much you can do to change their
settings.
That's it for Topic 101. I'll let you know if I find anything more in
subsequent topics.
