This chapter describes the devctl() commands that apply to embedded transaction filesystems. For more information about ETFS, see "Embedded transaction filesystem (ETFS)" in the Filesystems chapter of the System Architecture guide, and the entries for fs-etfs-ram and etfsctl in the Utilities Reference.

Note: Some of these commands require a file descriptor that corresponds to the filesystem partition, /dev/etfs2, not to the raw partition, /dev/etfs1.
