You can use -t weed on mount command:
mv weed /sbin/mount.weed
mount -t weed fuse /mnt -o "filer=localhost:8888,filer.remote=/"
Or you can use -t fuse on mount command:
mv weed /sbin/weed
mount -t fuse.weed fuse /mnt -o "filer=localhost:8888,filer.remote=/"
mount -t fuse "weed#fuse" /mnt -o "filer=localhost:8888,filer.remote=/"
To use without mess with your /sbin:
mount -t fuse./home/user/bin/weed fuse /mnt -o "filer=localhost:8888,filer.remote=/"
mount -t fuse "/home/user/bin/weed#fuse" /mnt -o "filer=localhost:8888,filer.remote=/"
To check valid options look "weed mount --help"
`,
