>Description:
When configuring an encrypted swap partition, I found an error in the fstab man page documentation.  Search for "eli" in the man page.  It will go to the section where "fs_type" is being described.  In the middle of that paragraph, it says:

"Swap entries on .eli devices will cause automatic creation of encrypted devices.  The ``ealgo'', ``aalgo'', ``keylength'', and ``sectorsize'' options may be passed to control those geli(8) parameters."

The ``keylength'' paramater is an invalid option which did work when I used it in the fstab file.  I found the SVN commit (r252310) where the key length parameter was documented.  It should be ``keylen''.  Using this spelling of the parameter, I was able to successfully set the key length for the encrypted swap partition.
>How-To-Repeat:

>Fix:
Update the documentation to spell the key length option as "keylen".
