Is it possible to mount(8) an EXT4 type image/fs?

Greetings all,

I'm in need of mounting a file that is an EXT4 (Linux) file system. I've used md(4) to (re)create the system: # md -a -t vnode -f recovery.img -u 1, which creates /dev/md1. But all attempts to mount it fail.
# mkdir /mnt/recovery, # mount /dev/md1 /mnt/recovery fails (invalid...). # mount -t ext2 /dev/md1 /mnt/recovery fails, and crashes, as does # mount -t ext4 /dev/md1 /mnt/recovery.

Also, I am unable to find mount_ext* on any of my RELENG_8, or RELENG_9 boxes. Has it been removed?

Thanks, for all your time, and consideration.

Thanks for the reply @pkubaj! Bummer. So it looks like FreeBSD has removed support for Linux file systems. :( What next, the Linux ABI from the kernel?

I guess I'll need to import source from a RELENG_6 branch, so I can get that support back in mount(8) for recent versions of FreeBSD.

Thanks again, @pkubaj.
