+eCryptfs is a cryptographic stacked Linux filesystem. eCryptfs stores
+cryptographic metadata in the header of each file written, so that encrypted
+files can be copied between hosts; the file will be decrypted with the proper
+key in the Linux kernel keyring. There is no need to keep track of any
+additional information aside from what is already in the encrypted file
+itself. You may think of eCryptfs as a sort of "gnupgfs", or "gnupg as a
+filesystem".
+
+On Slackware, the Slackbuild script does not install the mount helper binaries
+into /sbin, but to /usr/sbin. Because of this, using `mount -t ecryptfs` won't
+work, and you must call the `[u]mount.ecryptfs*` binaries explicitly.
+
+For an unprivileged user to use the `[u]mount.ecryptfs_private` executables,
+it is necessary to set the suid bit on them, which the Slackbuild script also
+does not do.
