How to install a mountpoint directory from an rpm?

[David Howells]

Hi,

I need to install a directory (/afs) that will be a mountpoint that a systemd
service (also installed in the rpm) will mount upon.

What's the best way to encode this in the specfile?

I did have:

	%files
	/afs

but that doesn't upgrade correctly.  Someone gave me another way to do it:

	%post
	%systemd_post afs.mount

	# Create /afs directory if it doesn't exist
	if [ ! -d /afs ]; then
	    mkdir /afs
	    chown root.root /afs
	    chmod 0755 /afs
	    [ -x /usr/sbin/restorecon ] && /usr/sbin/restorecon /afs
	fi

	%files
	%ghost %dir /afs

but rpmlint complains about the chown:

	kafs-client.x86_64: W: dangerous-command-in-%post chown

The git repo is here:

	http://git.infradead.org/users/dhowells/kafs-client.git/shortlog/refs/hea...


The second patch from the top is the one that tries to fix the mountpoint dir
installation issue ("spec: Treat /afs special").

Thanks,
David
