[pkg-cryptsetup-devel] Bug#967922: initramfs-tools-core: /run/cryptsetup should be configure with /usr/lib/tmpfiles.d/cryptsetup.conf

[Diego Escalante Urrelo]

Package: initramfs-tools-core
Version: 0.137
Severity: normal
X-Debbugs-Cc: diegoe at gnome.org

cryptsetup expects the `/run/cryptsetup` directory to exist, and
according to upstream the preferred way to get it to exist is with a
tmpfiles.d file:
  https://gitlab.com/cryptsetup/cryptsetup/-/merge_requests/99#note_390506222

`initramfs-core-tools` however just creates it manually:
```
/usr/share/initramfs-tools /scripts/local-top/cryptroot:
    # Create locking directory before invoking cryptsetup(8) to avoid warnings
    mkdir -pm0700 /run/cryptsetup
```

`dracut` does something similar in its scripts, but apparently in my
system systemd takes over and said script is never run, or ran too late?

```
/usr/lib/dracut/modules.d/90crypt/cryptroot-ask.sh:
    mkdir -p -m 0700 /run/cryptsetup
```

So, I believe perhaps the above directory might follow upstream
recommendation and be created in a tmpfiles.d configuration file.

Note that /usr/lib/tmpfiles.d/cryptsetup.conf is installed by
`cryptsetup-bin`.

A similar bug was opened for `dracut`:
