[Fedora-i18n-bugs] [Bug 1377367] fontconfig cache in /var incompatible with ostree model; unable to `rpm-ostree install emacs`
by Red Hat Bugzilla

--- Comment #12 from Matthew Miller <mattdm(a)redhat.com> ---
I agree with Colin's assessment that the FHS doesn't really cover this
situation well. From the section on /var:
/var is specified here in order to make it possible to mount /usr
read-only. Everything that once went into /usr that is written to
during system operation (as opposed to installation and software
maintenance) must be in /var.
But here, we're talking about stuff that is written specifically and only
during "installation and software maintenance". That's just not
well-accounted-for in the spec. Generate-at-build-time as I suggest above might
(I hope) work for fontconfig, but it won't for /etc/ld.so.cache -- and I guess
that living in /etc may be a reflection of the above problem.

Rather than moving the cache around -- or, I guess, in addition to it, but
obviating an concern about FHS or dyanamic, unmanaged files in /usr, could we
just pregenerate the cache files at _build_ time rather than install time? They
appear to be arch specifc (well, word size and order specific) but not really
host-specific.
Bonus: faster system install (when not using ostree; I guess faster ostree
generation too).

There's many other derived caches in /usr. gtk-update-icon-cache is one
offhand.
GNU info pages (`install-info`). kernel modules (depmod -a).
Remember that in the ostree model:
https://ostree.readthedocs.io/en/latest/manual/adapting-existing/
Things like the RPM database are also moved to /usr/share/rpm.
OSTree also *enforces* that /usr is read-only at runtime - but with rpm-ostree,
we construct a new tree on the client side, and run %posts there with it
mutable, then it's sealed back up at runtime.
An important thing to keep in mind with the FHS is that they tried to push for
having /usr be NFS mountable, which Fedora (and all systemd systems), don't
support. It's just not relevant - it's easier to NFS mount /, and do something
like ostree on the server to dedup the /usr content between different hosts.
Basically, the FHS requirements are from a previous mindset - the
https://freedesktop.org/wiki/Software/systemd/separate-usr-is-broken/ merge
pushed the semantics for /usr in a different direction, and OSTree goes much
farther with it.
The main concern I have here about breaking things is more around upgrades for
people who are using yum/dnf on the host. I could probably change rpm-ostree
to include an e.g. `OSTREE_SEMANTICS=1` environment variable, and the
fontconfig %post could key off that.
