We made it free software so that it enables as many users as possible to use their computer in freedom, and so that distributors can adopt it despite our disrecommendation. I don't regret that they have the practical means to disagree with us and take a different path. It's precisely the freedom we wanted them to benefit from!

It takes up about 60 sectors of the 64 sectors of the embedded area. I guess you speak about truecrypt. In this case the solution I would recommend is to make grub load truecrypt's embedding area from a file on the disk (it probably can be extracted from truecrypt w/o installing booter). It's not a difficult task, just nobody did it yet (volunteers are welcome). Beware that truecrypt is distributed under a license which has legal danger to the end user. https://fedoraproject.org/wiki/ForbiddenItems#TrueCrypt Of course it's your choice to use it or not but I would suggest to avoid such software especially for the data you need to protect It is not truecrypt. I would argue that a full disk encryption product should be in the boot sector/embedded area and everything else, even grub should load after it. Obviously your encryption solution does not encrypt the linux volume which you boot using the USB stick so it has no reason to be loaded when loading Linux, it can only cause harm by trying to decrypt what is not encrypted.

You make a assumption that the encryption program would cause harm. It does not. One specifies which partitions to encrypt/decrypt and it leaves the rest alone. It's loaded uselessly. Actually normally there is no reason to encrypt any of the files grub accesses. But authenticating files is needed. (encryption doesn't prevent attacker from modifying files) Encrypting is to keep secret MAC or signatures is to keep unmodified. GRUB and most OSes we support are free software so there is no reason to keep them secret. Even proprietary for kernels you have, the binaries aren't secret. There are two reason full disk encryption exists: 1) I have everything encrypted is a good confidence-giving sentence and good for marketing 2) If you encrypt everything you have no risk of forgetting encrypting something (typical examples: swap, /tmp, /var/tmp). This renders the approach fool-proof and easy to configure Also as Grub can access the disk drives by various means (BIOS, PCI device driver, ...) the encryption software would have to hijack all these access paths transparently which I can't imagine happening. One would obviously need grub to only use BIOS calls and no direct PCI device access for it to work together with the whole disc encryption program in pre-boot stages. The only reason we keep BIOS calls by default is that our own drivers don't work in all configurations. Alternatively, one would have to add encryption support into grub itself that is not a good idea. We have patches to do so. While encrypting a part of bootloader and a kernel isn't security-improving, it renders encrypted configuration easier (no need for separate /boot). So I'm favorable to it.

Re: [GITGRUB] New menu interface (implementation)
Hello
2009/9/25 Bean bean12...@gmail.com:
Hi,
Update:
Some adjustment to data representation. For example:
background = /splash.png
means loads splash.png, no extra handling if loading fails (text mode
or file not found)
background = /splash.png,,blue
means loads splash.png, if it fails, replace it with rect that has
blue background
This sounds reasonable for a background image. The background can be
also used for transparent parts of the image. For a label icon the
background should be probably taken from the label, including
transparent background or image background. If the icon fails to load
the size is zero unless explicitly scaled.
Add new number format to specify size for both graphic and text mode:
space = 10/0
I would prefer if the spacing would not need to be specified
separately for text mode and graphics mode.
I hope I can get to creating some layout mockups so that we can see if
that is feasible.
10 pixel in graphic text, 0 in text mode
New layout manger, it support the following parameters:
columns
valign
halign
width
height
vspace
hspace
vmargin
hmargin
width/height is the size of widget, if it's not set, the size is
calculated automatically using the size of child widgets
For sizing two modes are useful: the minimum sizing that assigns the
size required to display all content and the maximum sizing that
expands the widget as much as possible. If width = 100% means that any
siblings are not displayed because the widget occupies exactly the
available space then a different notation would be useful for taking a
share of the available width.
vmargin, hmargin is the distance between horizontal and vertical
border, positive value is from left/top, while negative value is from
right/bottom, for example:
panel
{
vmargin = -0
hmargin = -0
}
places the panel in the bottom right corner.
How does this resolve the problem of setting the top, left, bottom and
right margin without knowing the size (width, height) of the panel?
I know that when panel is drawn the size is known but the size might
not be known when the configuration is written (different screen sizes
or label lengths). Setting the size (width, height) might be
appropriate in some cases but in most it should be calculated
automatically so that the layout fits in the available space.
I might want a bit of space (like 0.5 em or 0.5c) around a label so
that the label text is not sticking to the border as it was in the
last demo.
If I have a background picture over which I want to draw the menu and
it has a designated area for this I can either measure the menu
position as x,y,width, height or as top, left, bottom, right. The
latter has the advantage that if I decide to allow scaling the picture
I can measure the margin in % and the rounding error for each border
is the same. For x,y,width,height the rounding error of the bottom
corner is twice as large.
In the general case I would want to avoid the menu sticking to the
border of the screen which again calls for a margin.
Here is a sample config file that shows different valign/halign
combination, the image file is inside the previous menu.zip.
screen
{
halign = center
valign = center
columns = 3
This is not nice because when you add a new panel it wraps to the next
row. For most uses grouping panels in a single direction seems more
useful. When they have some logical order that order is preserved when
a new panel is added.
background = /menu/back.png
panel
{
background = ,blue
hspace = 10/0
vspace = 5/0
halign = left
valign = top
width = 28%
height = 28%
Calculating this value is error prone and redundant since it is the
same for all panels.
Thanks
Michal

Support for howmany option in grub2
Hello,
I am using Debian GNU/Linux as my primary system. As a loader I am using GRUB.
Actually I have upgraded to GRUB2. I don't know, if it was feature of original
(legacy) GRUB or it was functionality provided by debian scripts (update-grub),
for generating menu.lst. There was feature - howmany. This option specifies
number of kernels, that user wants to have in boot menu. Script, that modifies
menu.lst, use this variable. I like this feature, because I have usually more
kernels, but I want to see only last two versions in GRUB menu. I have created
patch, that add support for this to /etc/grub.d/10_linux. I have created this
patch against version shipped with Debian (1.97~beta3-1) - I don't know if
there are some Debian specific modifications. Also there should be variable
GRUB_HOW_MANY propagated from /etc/default/grub (my patch don't do
this).
Kernel and it's rescue variant is counted as one kernel.
I have already reported this bug to Debian BTS:

Re: [GITGRUB] New menu interface (implementation)

Add new number format to specify size for both graphic and text mode:

Hi,
You can still use character unit as:
space = 1
But the problem is that minimum value is 1. In text mode, 1 character
size is significant. We don't want to spend valuable space for
parameters like vspace and hspace. But in graphic mode, we can afford
some pixel on spacing.
10 pixel in graphic text, 0 in text mode
New layout manger, it support the following parameters:
columns
valign
halign
width
height
vspace
hspace
vmargin
hmargin
width/height is the size of widget, if it's not set, the size is
calculated automatically using the size of child widgets
For sizing two modes are useful: the minimum sizing that assigns the
size required to display all content and the maximum sizing that
expands the widget as much as possible. If width = 100% means that any
siblings are not displayed because the widget occupies exactly the
available space then a different notation would be useful for taking a
share of the available width.
Yep, I have plans for the min_width/min_height/max_width/max_height property.
vmargin, hmargin is the distance between horizontal and vertical
border, positive value is from left/top, while negative value is from
right/bottom, for example:
panel
{
vmargin = -0
hmargin = -0
}
places the panel in the bottom right corner.
How does this resolve the problem of setting the top, left, bottom and
right margin without knowing the size (width, height) of the panel?
I know that when panel is drawn the size is known but the size might
not be known when the configuration is written (different screen sizes
or label lengths). Setting the size (width, height) might be
appropriate in some cases but in most it should be calculated
automatically so that the layout fits in the available space.
It'd work as expected, you can see it by setting the width/height of
the last panel to 28%/28%, it'd still stick to the border. The program
do this in two steps, first the size, then the position, it allows to
the widget to change the size before position is calculated.
I might want a bit of space (like 0.5 em or 0.5c) around a label so
that the label text is not sticking to the border as it was in the
last demo.
You can do this with vspace/hspace. The last panel looks compact as it
does specify width/height so that the minimum required size is used.
If I have a background picture over which I want to draw the menu and
it has a designated area for this I can either measure the menu
position as x,y,width, height or as top, left, bottom, right. The
latter has the advantage that if I decide to allow scaling the picture
I can measure the margin in % and the rounding error for each border
is the same. For x,y,width,height the rounding error of the bottom
corner is twice as large.
In the general case I would want to avoid the menu sticking to the
border of the screen which again calls for a margin.
Actually, when vmargin and hmargin is positive number, it's exactly
the same as x,y, but it also allows to stick to other borders, which
is impossible for x,y without setting the size.
Here is a sample config file that shows different valign/halign
combination, the image file is inside the previous menu.zip.
screen
{
halign = center
valign = center
columns = 3
This is not nice because when you add a new panel it wraps to the next
row. For most uses grouping panels in a single direction seems more
useful. When they have some logical order that order is preserved when
a new panel is added.
For single row, set
columns = 0
For single column, set:
columns = 1
background = /menu/back.png
panel
{
background = ,blue
hspace = 10/0
vspace = 5/0
halign = left
valign = top
width = 28%
height = 28%
Calculating this value is error prone and redundant since it is the
same for all panels.
This is just a demo, in fact, you can skip the width/height parameter
and it will calculate the minimum size for you. But in this case, you
can't see the valign/halign property in action inside the panel.

viewport for drawing to avoid these overflows. Unfortunately, this is

Hello
I tried looking at the overflow but i seriously have no idea what are
all these regions the gfx_region_update_* gets.
There is some scn_x and scn_y but these do not seem to be the screen
coordinates of the region.
If I could tell for what region I am doing the update (that is the
x,y,width,height of the region in screen coordinates) I could set the
viewport accordingly so that the content does not overflow.
At the very least the patch replicates the same breakage in much fewer
lines of code.
Thanks

If nobody else does then I'd be interested in doing so myself, although I will not be able to start for a month or two from now. Is there any guild lines for porting GPLv2 code to GRUB2? I've looked at the GRUB2 wiki but very few things are documented there (http://grub.enbug.org/). I'd like to see what it would take to port the patches. If I can afford it, I'd like to try. I assume you mean GPLv2-only code (as opposed to GPLv2-or-later). First step would be to contact the copyright holders and ask them to relicense under v3-compatible terms (e.g. GPLv2-or-later). Chances are they didn't chose these terms as an act of hostility, but were simply being zealous about allowing something before they knew what it is. If that doesn't work, we'll always have Par^W clean room (http://en.wikipedia.org/wiki/Clean_room_design). Edward's patch (stage2/fsys_btrfs.c) is declared GPLv2-or-later. But stage2/btrfs.h (which is extracted from btrfs-progs) is GPLv2-only. At the point, we only need a clean room for btrfs.h, right? And I'm not sure what a clean room design in GRUB2 looks like.

There is some scn_x and scn_y but these do not seem to be the screen coordinates of the region. If I could tell for what region I am doing the update (that is the x,y,width,height of the region in screen coordinates) I could set the viewport accordingly so that the content does not overflow. At the very least the patch replicates the same breakage in much fewer lines of code. Hi, I've tried to use viewport method before, but there seems to be some bug in video system that the font doesn't drawn at all. I can see the text when removing grub_video_set_viewport, and the position is correct. -- Bean gitgrub home: http://github.com/grub/grub/ my fork page: http://github.com/bean123/grub/ ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel

Hi, No, the default unit is still character. In fact, I've removed to p unit that's specific to graphic mode, now if you want to set pixel size, you need to use the '/' method like 100/1 (100 pixels in graphic mode, 1 in text mode). Also when the vspace is set to 1 instead of 5/0 the text does not fit into the panel but is still drawn. The widgets should really use viewport for drawing to avoid these overflows. Unfortunately, this is probably not available in text mode but it should not be hard to add. There are viewport function in region, available in graphic and text mode. I can use it to limit the widget. For sizing two modes are useful: the minimum sizing that assigns the size required to display all content and the maximum sizing that expands the widget as much as possible. If width = 100% means that any siblings are not displayed because the widget occupies exactly the available space then a different notation would be useful for taking a share of the available width. Yep, I have plans for the min_width/min_height/max_width/max_height property. That's probably not the thing I had in mind. Well, perhaps setting max_width to 100% would do what width=* in HTML. Currently, if you don't set width/height property, it would assign minimum size automatically, width = 100% means it has the same width as its parent, the child widget would reposition according to that. I don't want to set the size of anything, ever. There still should be a way to get borders into the layout. But layout ready has borders, just set the top_left/top/../bottom property. By stick to the border I mean the ugly situation when the element content touches the border visually blending with it. My meaning of sticky is that the widget has a constant distance from one of the border, for example, -1, -1 means it's -1c -1c from the bottom right corner. is impossible for x,y without setting the size. AFAIK it's still impossible to make a panel with the same distance from each border of the screen without setting its size manually. All my attempts failed miserably. Doesn't the demo work ? The last panel only sets vmargin and hmargin, width and height is calculated automatically and it's in the bottom right corner. The other problem is that the text is not shown for some reason in the demo with Debian/Ubuntu/Gentoo and the blue squares are still shown in text mode. The title property has renamed text, and to remove the blue square, just change image = /menu/ubunti.png,,blue to image = /menu/ubunti.png as the previous one would create a rect if image can't be loaded. For single row, set columns = 0 For single column, set: columns = 1 These look sensible except 0 meaning infinite is somewhat needlessly confusing. What's columns = 3 for other than showing a demo? Which could be done in other ways, anyway. There are numerous bugs in the table layout already, and if you go with tables there's going to be no end of them. The table has no colspan/rowspan which people will likely expect of tables. The last cell that has hmargin/vmargin is ignored by the table layout to the point that it can overlap other cells. The cells in the last row are aligned differently than the above cells because the number of cells considered for the table layout is not divisible by the number of columns. hspace/vspace is ignored when the valign/halign is center. Last but not least tables which are a packing of elements modulo number of columns are fundamentally broken way of rendering a set of elements. A table is called for when you have elements that are sorted into a two dimensional space of indices. Then you can find a particular element by finding its row and column index. We don't have that kind of data in Grub. It is completely feasible to have multiple one-dimensional lists side by side or one below another. For example a row of bootloader icons and a row of tool icons. There is no relationship between the elements in the two lists so there is no problem with the lists scrolling independently. When a new bootloader is added the tools are not affected. Similarly you can have a list of Debian kernels in one column and a list of Gentoo kernels in another. Again they are independent of each other. Adding a Debian kernel should not affect Gentoo kernels nor the other way around so this is not a table. Even HTML does not have a mod N table. It has TR and TD. Managing a mod N table in a sensible way is a nightmare. When you actually have a table then you have to make sure you add a row at a time and pad with empty cells to preserve the columns. When you have a one-dimensional list adding to the middle of the list reflows all the later elements so it is not obvious what was changed
