There is no REQUIREMENT that a host key have a particular file name is there? The sshd_config provides for setting one explicitly and doing so seems to cause no problems with ssh connections that I have yet encountered.
The "system_u" vs. "unconfined_u" is inconsequential. That just comes from process that set the label.
Looking at the file labeling rules, only the 7 specific file names get a type of "sshd_key_t", and, strangely, not the /etc/ssh directory itself, so /restorecon/ will just make any other file there inherit the type of the directory, which is "etc_t". At first glance that looks like a bug, but perhaps there is come reason for that.
If you want to use a non-default filename for something, so that the pre-defined regexes which restorecon uses won’t match on it, you can either add a new regex to the policy which will be persistent or just use chcon to set the type manually. — Mark Tinberg mark.tinberg@wisc.edu
