Who is using that file system? Ideally if "we" are the last user of the file system it should be safe to mount ro it as well. In general this happens when there is a "too smart to fit /" filesystem in use. In general that means that the same stuff used in /usr to mount it should live in the initrd... In general deprecating split-/usr moves the problem in in supporting fat initrds to begin with. (I guess needing a boot filesystem that is fuse based and needs rabbitmq or postgresql might be extra fun btw). > This service only exists in the Linux world; there is no equivalent in > OpenRC for any other operating systems we support.

I think any fuse-supporting system should have it for more or less obvious reasons (see the evil example above). lu
