[DSE-Dev] Bug#1049428: selinux-policy-default: statd and mountd fail to start with fixed ports

[Colin Simpson]

I ran something similar for the upstream report. 

Okay audit2allow now says:
#============= rpcd_t ==============
allow rpcd_t nfs_port_t:tcp_socket name_bind;
allow rpcd_t nfs_port_t:udp_socket name_bind;
allow rpcd_t nfsd_fs_t:dir search;
allow rpcd_t nfsd_fs_t:file { open read };

Or the raw log if that's more what you want:
