| H A D | namei.c | 79aa2849 Fri May 19 12:21:20 CDT 2023 David Howells <dhowells@redhat.com> cachefiles: Allow the cache to be non-root
Set mode 0600 on files in the cache so that cachefilesd can run as an
unprivileged user rather than leaving the files all with 0. Directories
are already set to 0700.
Userspace then needs to set the uid and gid before issuing the "bind"
command and the cache must've been chown'd to those IDs.
