I think that a better thing to do is to use "--" on the file_contexts entry
for an executable file and have any sym-links with similar named get bin_t or
sbin_t. The contents of a sym-link are almost never of any relevance to the
security of the system, but adding more rules increases the size of the
policy and the work for all of us. Also as a side-affect specifying the
class of the object to be labelled makes setfiles run faster.
I have attached a patch which adds -- to all types ending in _exec_t. It also
fixes some bugs in the spamassasin policy and adds a couple of other file
contexts things as well.
