Check old tmpfiles.d when removing package
Browse files Browse the repository at this point in the history
When removing package, will also remove the generated tmpfile
config under the rpm-ostree tmpfiles.d directory. Since coreos#4697,
we use the new directory like `usr/lib/rpm-ostree/tmpfiles.d`, but
for old `usr/lib/tmpfiles.d`, failed with `error: opendir(usr/lib/
rpm-ostree/tmpfiles.d): No such file or directory`.

With this patch, check if `usr/lib/rpm-ostree/tmpfiles.d` does not
exist, will use old `usr/lib/tmpfiles.d` instead.
Also needs coreos#4727.
Fixes: fedora-silverblue/issue-tracker#523
