FreeNAS Code

Allow selecting the key length of the cryptographic algorithm used to encrypt a disk (FR 2779692).

Fix false positive bug while detecting disk mount state (BR 2706994). Thanks to desummoner for the patch.

Mounting NTFS on FreeNAS 0.7 fails due the following:

Note that in FreeBSD 7.x, mount(8) has a fixed (hard coded) list of external
mount_XXX programs that can be called, so to make this work you have to do one
of the following:

1. Rename /sbin/mount_ntfs, symlink ntfs-3g as the former, and use just "ntfs"
as the type in /etc/fstab.
$ mv /sbin/mount_ntfs /sbin/mount_ntfs-kern
$ ln -s /usr/sbin/mount_ntfs-3g /usr/sbin/mount_ntfs
2. ...

force option is not used anymore in NTFS-3G 2009.2.1 (BR 2702170). Thanks to skygunner6.

Remove misc mount parameter for mount_msdos because they permit settings user permissions configured via WebGUI.

If mount fails log error message to syslog.

Relocate code.

Mention file system type if mount fails.

Add UDF ISO support (should be work). Testing was not possible because available UDF ISO's were not detected as UDF using 'file' on Linux and Freebsd 7.1.

Delete GEOM metadata before installation.
