Struct MountInfoRootRewrite 

Source 
pub struct MountInfoRootRewrite {
    pub raw_mount_id: u64,
    pub deterministic_root: Vec<u8>,
    pub raw_root_prefix: Option<Vec<u8>>,
    pub deterministic_root_prefix: Option<Vec<u8>>,

    pub deterministic_mountpoint_prefix: Option<Vec<u8>>,
}
Expand description

One mount row whose kernel-private root must be replaced before it becomes guest-visible.

The CLI populates this only after proving, with held file descriptors in the completed mount namespace, that the mount is one Hermit created. The raw mount ID is namespace-local, so these entries are valid only for the one container run whose configuration carries them.

Fields§

§raw_mount_id: u64

Mount ID read from the held target descriptor’s /proc/self/fdinfo.

§deterministic_root: Vec<u8>

Stable guest-visible replacement for the row’s root field.

§raw_root_prefix: Option<Vec<u8>>

Exact encoded kernel root prefix used for descendant mount rows.

This is present only for a proven private /tmp. Mounts installed below that directory before it is bound over guest /tmp otherwise expose the randomly named backing directory in mountinfo field 5.

§deterministic_root_prefix: Option<Vec<u8>>

Guest-visible prefix replacing raw_root_prefix.

§raw_mountpoint_prefix: Option<Vec<u8>>

Exact encoded host path prefix used for descendant mountpoints.

§deterministic_mountpoint_prefix: Option<Vec<u8>>

Guest-visible prefix replacing raw_mountpoint_prefix.
