Summary0018567: SELinux is preventing /usr/libexec/snapd/snapd from 'search' accesses on the directory /proc/sys/fs/binfmt_misc.
DescriptionDescription of problem:
SELinux is preventing /usr/libexec/snapd/snapd from 'search' accesses on the directory /proc/sys/fs/binfmt_misc.

***** Plugin catchall (100. confidence) suggests **************************

If you believe that snapd should be allowed search access on the binfmt_misc directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'snapd' --raw | audit2allow -M my-snapd
# semodule -i my-snapd.pp

snapd is not provided by Centos so you'd better file a bug against the provider of the package ( EPEL, probably ).
