5.3 FHS Linux Standard Directory Tree
I have noticed that the link to the download of current "Filesystem Hierarchy Standard" (version 2.3) appears to be dead on the related page of the LFS201 course.
A quick web search yielded a link to the new 3.0 standards (published March of 2015) at https://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.pdf
The data page of Course LFS201 located under the header "5.3 FHS Linux Directory Tree" didn't get updated yet and it will be corrected to show the new 3.0 standards, instead of having the dead link to the 2.3 standards.
I have emailed the support team and confirmed the course contains a dead link and is out of date on this topic. The need for an update has been documented and will be addressed in the next release of the courseware. The update will not be displayed until a new version of the course is released, but they are aware of the issue.
