Bug 666222 – sci-physics/root: please respect FHS

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Benda Xu 2018-09-14 11:11:13 UTC]

Hi Amadio,

The root ebuild is not in a good shape in that /usr/lib/root has a couple of directories underneath that should go to /.  For example, /usr/lib64/root/6.14/etc and /usr/lib64/root/6.14/share.

That makes relevant files hard to find and causes surprises to users.

Hi Benda, I am aware of it. See slide 18 of the presentation below :-)

We have some issues that I need to fix first before updating the package in Gentoo, but this is high in my priority list.

https://sft.its.cern.ch/jira/browse/ROOT-9403

ROOT installs too many things into /etc if we install it into /usr, so I thought it would be better to install into some other prefix (similar to dev-lang/R) while I work on fixing these issues upstream.

Thanks, hope you guys can achieve these goals soon.

sci-physics/root-6.28.00 and above are using standard install locations.
