Using the X-mount.idmap option in fstab

[uleysky]

I want to automatically mount cephfs from a remote cluster on my machine. Since the users and groups on the local and remote machines are different, I use idmap. However, there is no way to add such a mount point to /etc/fstab. User and group mappings must be separated by a space, which results in a read error. Specifying the X-mount.idmap option twice does not work. Specifying a file with mappings as a parameter results in the "Inappropriate ioctl for device" error.

In my Gentoo I solved the problem by making a patch that adds "_" as an alternative separator. But I would like this problem to be solved properly.

You can use name="value", for example: X-mount.idmap="u:1000:0:1 g:1001:1:2 5000:1000:2"
