Libguestfs - Feb 2022 - [libguestfs PATCH 3/3] TODO: remove "Better support for encrypted devices"

LUKS support used to work best if the LUKS device resided on a partition,
and contained a Physical Volume for an LVM Volume Group. This scheme, also
called LVM-on-LUKS, is commonly created by installers of various Linux
distributions. (See RHBZ#1451665.)

Libguestfs now also supports the scheme wherein the LUKS device resides on
an LVM Logical Volume, and contains a filesystem. This is called
LUKS-on-LVM, it is the inverse of the above scheme, and is created by
installers of other Linux distributions. (See RHBZ#1658126.)

Both schemes are now decrypted by libguestfs-based utilities when
inspection is enabled (such as in "guestfish -i", virt-inspector,
virt-v2v), through the inspect_mount() function in utilities written in C,
and through the "inspect_decrypt" function in ones written in OCaml.

We don't seem to need an API like "list-luks-devices", as
"list-dm-devices" returns decrypted (i.e., opened) LUKS devices too;
for
example, in the LUKS-on-LVM case:
> ><fs> list-dm-devices
> /dev/mapper/luks-0d619854-ccd5-43b1-8883-991fec5ef713
> /dev/mapper/luks-4e9e7a6f-a68c-42fd-92b4-8f4f2579a389
Thus, the subject TODO section is now out of date, and it's unclear what
remains "to do" there; let's just remove the section.

-Better support for encrypted devices
-------------------------------------
-
-Currently LUKS support only works if the device contains volume
-groups.  If it contains, eg., partitions, you cannot access them.
-We would like to add:
-
-  - Direct access to the /dev/mapper device (eg. if it contains
-    anything apart from VGs).
