# Remap-UIDs/GIDs is the mapping from UIDs/GIDs as they should appear inside of

# Remap-User/Group is a user name which can be used to look up one or more UID/GID

# ranges in the /etc/subuid or /etc/subgid file.  Mappings are set up starting

# with an in-container ID of 0 and then a host-level ID taken from the lowest

# range that matches the specified name, and using the length of that range.

# Additional ranges are then assigned, using the ranges which specify the

#     All files/directories get set with 0700 permissions.  The owner has rwx

#     access to the files. No other users on the system can access the files.

#     This setting could be used with networked based homedirs.

#  "shared": it is equivalent to 0755.

#     The owner has rwx access to the files and everyone else can read, access

#     and execute them. This setting is useful for sharing containers storage

#     with other users.  For instance have a storage owned by root but shared

#     to rootless users as an additional store.

#     NOTE:  All files within the image are made readable and executable by any

#     user on the system. Even /etc/shadow within your image is now readable by

#     any user.

#

#   OCTAL: Users can experiment with other OCTAL Permissions.

#

#  Note: The force_mask Flag is an experimental feature, it could change in the

#  future.  When "force_mask" is set the original permission mask is stored in

#  the "user.containers.override_stat" xattr and the "mount_program" option must

#  be specified. Mount programs like "/usr/bin/fuse-overlayfs" present the

#  extended attribute permissions to processes within containers rather then the

#  "force_mask"  permissions.
