Linux default install layout, Filesystem Hierarchy Standard and /opt.

I, Valdes () Linux default install layout, Filesystem Hierarchy Standard and /opt.

Reply Threaded

Hi all,

I notice that the latest Plone 3.3.1 installs by default in
/usr/local/Plone rather than the previous /opt. I am facing similar
questions with Astronaut Veterans Affairs VistA installer suite and am
wondering why the decision was made and does the new way conform to
File Heirarchy Standard:

I have no idea why the change was made, but I would certainly agree that it
does conform to the FHS. The Wikipedia entry is wrong about the purpose of
/usr/local! See http://www.pathname.com/fhs/pub/fhs-2.3.html

Thanks, it seems that it is closer to FHS but it still has Data.fs in /
usr which is supposed to be a no-no, it is supposed to be in /var. I
have a similar situation with Astronaut. I'd rather not scatter parts
of Astronaut over the file system but FHS would require me to do so.

The change was made for purely pragmatic reasons; believe it or not, there are still *nix distributions out there that do not have an /opt tree. Use the Unified Installer's --target=... option to drop the system where you prefer.

And, after install, go ahead and move the var folder of the new installation to wherever it belongs, then symbolically link to it from your buildout directory.

This is true - variable data shouldn't be in /usr (it should be possible to
mount the /usr filesystem read-only).

I _would_ rather scatter pieces of an app over different filesystems,
precisely because I want to be able to mount /usr read-only, but it's a
trade-off.

In general what advantages are there to being able to mount /usr as
read-only and have writable things in var?

In general how does one handle multiple instances using var?
