The ID-mapped mounts feature plays an important role in the containers world and becoming more and more adopted in different close areas. This feature was developed by Christian Brauner and almost from the beginning it supports ext4, xfs, btrfs and other local filesystems. In this talk we want to cover network/network-like filesystems support for idmapped mounts. Recently, we have finished the work on supporting idmapped mounts in cephfs, and we want to highlight next steps in converting more filesystems like fuse, NFS, etc.
