Looks like it.  I think leaving making it initrc_t would fix most of
your avc messages.

It certainly changed them. Here is the of the changing init_t to initrc_t

and the result of deleting the transition entirely (Jame's patch)

#============= init_t ==============
allow init_t self:unix_dgram_socket sendto;
allow init_t shell_exec_t:file { read execute execute_no_trans };

#============= initrc_t ==============
allow initrc_t etc_t:file write;
allow initrc_t lvm_control_t:chr_file write;
allow initrc_t var_run_t:sock_file create;

#============= insmod_t ==============
allow insmod_t kernel_t:process setsched;

#============= setrans_t ==============
allow setrans_t initrc_t:fd use;
