Disk encryption and installing new versions of Fedora

[Mike]

In the past year progress has been made with dm-crypt and luks being available
for F7 although with some residual bugs which were never resolved.

It is therefore possible to arrange to have F7 running with an encrypted swap
area, and encrypted /home for example.

I wonder what experience others have had with this?

The other question I have is to ask whether anyone has had problems when
installing F8 on a machine which has been running encrypted swap and 
encrypted /home?  

Ideally one should be able to do a clean install leaving the encrypted swap
as well as the encrypted /home in place as partitions separate from the root
partition.

Has anyone tried this?  Is Fedora set up to properly support disk encryption
in this way?  After all anybody running a laptop with sensitive information on
it would reasonably wish to use disk encryption to safeguard the information in 
the event of the laptop being stolen. I don't know whether RHEL is any better
at supporting this essential facility.

I would imagine that many companies might not allow employees to use a laptop
for work unless it had secure disk encryption?

Can any experts who know about this comment please?

If disk encryption using dm-crypt/luks is not fully supported then what tools 
or changes might be required within the distribution to properly support this
facility?  Is this going to get more support in F9?
