[Bug debuginfod/27783] file-based default DEBUGINFOD_URLS
https://sourceware.org/bugzilla/show_bug.cgi?id=27783 Frank Ch. Eigler changed: What|Removed |Added Resolution|WONTFIX |--- Status|RESOLVED|REOPENED --- Comment #2 from Frank Ch. Eigler --- In the context of fedora https://bugzilla.redhat.com/show_bug.cgi?id=1970312 we should reexamine this. Here's another idea. - retain /etc/profile.d/debuginfod* but change its behaviour: - instead of containing one hardcoded path, let it search a config file/dir such as /etc/debuginfod-urls.d/ and assemble the environment variable - the --with-debuginfod-urls=FOO elfutils option would arrange to drop in one file into this directory (say /etc/debuginfod-urls.d/elfutils.url) with the content FOO - other add-on distros (rpmfusion? ISVs? local administrator?) can do the same That way a local admin can remove or update or add more files. A user can of course still override it in their .profile. -- You are receiving this mail because: You are on the CC list for the bug.
