util-linux: Add findmnt

[seamusdemora (Seamus)]

findmnt is a very useful utility, but it's not included in the util-linux port. It would be really nice if it were possible to add it.

[raimue (Rainer Müller)]

The upstream project for util-linux does not provide all tools for all platforms. I would assume that findmnt relies on platform-specific APIs to read the list of mounts and therefore it is likely not supported on macOS at all.

[seamusdemora (Seamus)]

@Rainer: "I would assume..." What does that mean? Are you rejecting the request based on that assumption?

[kurthindenburg (Kurt Hindenburg)]

findmt currently doesn't build for me on Ventura. I'm not sure the code is portalbe enough to work on macOS.

[kurthindenburg (Kurt Hindenburg)]

I doubt this will happen; my machine doesn't have mntent.h and I'd assume others don't as well.

configure: WARNING: mntent.h header file not found; not building libmount
configure: WARNING: libmount disabled; not building libmount_mountfd_support
configure: WARNING: libmount disabled; not building findmnt

As far as I can tell it is not possible to build findmnt on macOS so I will close this ticket. If you want findmnt on macOS, you'll have to work with the developers of util-linux to make it macOS-compatible first.
