New Revision: 13179
Added:
incognito/trunk/root_overlay/usr/sbin/enable-persistent-vol
incognito/trunk/root_overlay/usr/share/applications/enable-persistent-vol.desktop
Modified:
incognito/trunk/TODO
incognito/trunk/root_overlay/etc/init.d/external-config-setup
incognito/trunk/root_overlay/usr/sbin/create-homevol
Log:
The persistent volume creation script is now even more user-friendly and informative. It's also possible to turn it that functionality off completely during boot and to re-enable it.

- Allow home dir on USB when booting from CD
Allow the home directory on a USB drive (or other media) when booting from the CD. This will require an optional menu if more than one possibility for a home directory is found.
-- Never create persistent home option on USB
-Make it possible to to permanently decline creating a persistent home partition during boot from USB (otherwise this will constantly be halting the boot process).
-This easily implemented by a "lock" file, i.e. NO_PERSISTANT on the USB root, created by external-config-setup when the users choses to never have a persistent home. external-config-setup will check for the existence of that file before prompting the user. Also, there should be a readily available script which resets this available on the KDE desktop and in the fluxbox menu.

Install mixmaster and mixmaster-smtp and integrate into mail clients. Remove mixminion-smtp.

KSirc isn't that user friendly. Konversation is probably better, wait for 1.1 release + make comprehensive server list incl. privacy and Tor related servers.

-Badly needed for performance. The autostart should check if it's installed. If not, prompt if it should be installed (plus describe benefits). Include kqemu windows install.

- Remove kmail?
We already have Thunderbird, so we could save space this way. Also, Torbutton is only for Thunderbird and it scrapes IP address/host from EHLO/HELO message. Don't know whether this is possible for kmail and that's serious if it's to be used for SMTP(s).

-If you want to use a hidden volume you must enter two differen passwords, one normal volume password and one hidden volume password in their respective input fields. The hidden volume password is the one you should use personally when starting __INCOGNITO__ which will give you access to the hidden volume. The other password you may give away to the authorities when under pressure as that will give them access to the normal volume and provide you with plausible deniability. Without the hidden volume password it is impossible to prove the existence of the hidden volume, so never give it away. This can save you if you live in a country where there
+A hidden volume offers you plausable deniability which is essential in case you live in a country where you must hand over encryption keys and passwords to the authorities when suspected for a crime (like in the UK). The hidden volume will reside in the free space of the normal volume, and you will have two different passwords; one that grants access to the normal volume and one that grants access to the hidden volume. The password for the normal volume can be given away to the authorities when they so demand, and as long as you keep your hidden volume password for yourself they cannot prove of its existence.
-If you only want to encrypt your data and not use a hidden volume, leave the hidden volume password blank. In that case, since you only have the normal password you should always use it.
+If you want to use a hidden volume, you should do all your real work within your hidden volume, which you access with the hidden volume password. Only occasionally should you log in to the normal volume (using the normal volume password) and do some \"normal\" things (i.e. no illegal or otherwise sensitive activites) so it looks like it is being used, otherwise the authorities might become suspicious when they discover that you haven't touched it. When you do that, just remember to not save much data on the normal volume as that can damage your hidden volume.
+You can use a weak and easy-to-remember password for the normal volume, but the hidden volume should have a password just as strong as any other password protecting sensitive data."
