## File Device printing after CVE-2026-34990 fix

After the fix, cupsd requires user to prepare the output file before printing
to prevent any unwanted overwrites or removals. For example for file /tmp/ps:

```
$ touch /tmp/ps
$ chcon system_u:object_r:cupsd_tmp_t:s0 /tmp/ps
```

cupsd after the fix requires the file to exist and changing the context is
for Selinux to allow the cupsd to write into it.
