conf.avail and conf.dyyyyyyyyyyyyyyy
Hi Nicolas,
Hi Behdad,
Thank you for reviewing it,
I like the direction of it.
The idea of having separate conf.avail and conf.d is that sysadmins can symlink/unlink entries into conf.d to enable/disable configuration for their system. This would only work if upgrading fontconfig/fonts rpms does not reinstate the unlinked symlink. However, last time I checked this was not working correctly. Can you check this first?
I didn't write it in the wiki, but as far as I understand rpm it is not possible to tell it "if this file/symlink does not exist do not install it". So this bit of conf.avail/conf.d design will never work on rpm systems. And even if it worked, what you'd actually need would be "if this file does not exist and was installed by a previous rpm" to handle initial deployment. Which starts to be real hairy. (more generally treating absence of an item as disabling this item is a broken computer pattern IMHO.)
However (someone please check this) it's probably possible to disable an entry permanently by creating a symlink with the same name pointing somewhere else (how does fontconfig reacts to /dev/null symlinks or symlinks pointing to empty files)? So having a repository of pre-deployed config snippets is fine with me.
Also (and this bit is traced on the wiki) as I understand the FHS /etc/.../conf.avail is a complete no-go and should be moved to /usr/share/something if we want to be clean. And that before /etc/.../conf.avail is duplicated in many packages.
