Merge lp:~ivoks/casper/casper-virtio into lp:casper

[Ante Karamatić]

At the moment, casper doesn't work with live system located on virtio device. This simple change makes that possible.

[Colin Watson (cjwatson)]

Could you please re-propose this for merging into lp:ubuntu/casper
rather than lp:casper, so that we get a useful merge diff? Thanks.

[Ante Karamatić (ivoks)]

Ups. Sorry about that.

+
+-h, -help		Display this help.
+-chroot=<root>		Chroot into <root> to apply profile settings, requires a
+			username to be specified, see below.
+-user=<username>	The user where a profile is to be applied, requires the
+			script to be run as root. If no username is given, it
+			is assumed that you wish to apply profile settings for
+			the current user.
+-l, -login		Apply some of the selected profile settings to the
+			login manager. Currently this is hard-coded to lightdm.
+			This requires root privileges.
+-i, -initramfs		Indicate that the script is being called from the
+			initramfs. Allows the script to assume some values
+			that can not otherwise be easily determined in an
+			initramfs environment. Requires that a chroot dir and
+			user name are specified. See above.
+-script			Create a script to be run at system boot that will
+			apply all settings for the specified user and for
+			login. This script will then remove itself. This is
+			needed to work around gsettings not working in a chroot
+			environment with no dconf service running.
+-d|-debug		Enable debugging output.
+<profilename>		The name of the profile you wish to apply, see below.
+
+The profiles currently available are as follows:
+high-contrast	For users with lesser visual impairments who only need a high
+		contrast theme, mouse cursor and icons.
+magnifier	For users with moderate visual impairments who require a screen
+		magnifier.
+blindness	Users who are partially or completely blind who require a screen
+		reader.
+braille		Users who are partially or completely blind who require a screen
+		reader and wish to use a Braille display.
+keyboard-modifiers
+		Users who have minor motor impairments who require slight
+		changes to the way their keyboard behaves.
+onscreen-keyboard
+		Users with motor impairments who require the use of an
+		on-screen keyboard.
