systems with a limited number of configurations. Therefore, if you
try rEFInd and run into bugs, please report them to me!</li>
- <li>I have little talent with graphics manipulation programs, so
- rEFInd's boot logo, such as it is, is pretty weak. If you have
- artistic talent and would like to create a rEFInd logo, please feel
- free to send it to me. I won't make any final decision about
- changes until at least June 30 of 2012.</li>
-
<li>rEFIt's original design, and hence rEFInd's design, enables easy
theming by replacing icon files. If you'd like to design a new
theme for rEFInd, feel free to submit it. I might or might not
rEFInd can't use the icon. The ability to scale images to the
desired size would be useful.</li>
+ <li>A way to set the color of the font would be useful for theming
+ purposes.</li>
+
+ <li>The program's font features could be greatly improved by enabling
+ use of a standard font format, by enabling use of non-ASCII
+ characters, and by enabling use of variable-width as well as
+ monospace fonts.</li>
+
<li>I would like to be able to specify the volume on which a boot
loader resides using a partition GUID value, but extracting a GUID
from the partition data is harder than extracting the volume's
the list, it will take precedence over the normal hard disk
default.</li>
- <li>Along the lines of the previous item, the default_selection might
- be expanded to support some form of specification of disk types, as
- in a special entry for any optical disk or any external disk, no
- matter what its name is.</li>

+ <li>I've been receiving reports of blank screens when using rEFInd on
+ some recent Mac models. I've investigated this with the help of one
+ user, and I suspect that Apple has made changes to its firmware
+ that are likely to affect just about any EFI program. I don't have
+ a definitive solution, but at least one user has reported that
+ removing rEFInd's drivers has caused the problem to go into
+ remission.</li>
+
<li>The <a href="http://www.rodsbooks.com/gb-hybrid-efi/">Gigabyte
Hybrid EFI</a> has a bug that causes the allegedly case-insensitive
<tt>StriCmp()</tt> function to perform a case-sensitive comparison.
Apple-specific EFI extension, and I know of no standard EFI way to
do it.</li>
+ <li>A couple of Mac users have reported that the brightness-adjustment
+ features in Windows don't work when Windows is booted via rEFInd,
+ but that these features do work when Windows is booted via the
+ Mac's built-in boot manager. Unfortunately, I have no idea what
+ causes this problem, I have no Windows installation on my one
+ (elderly) Mac, and I have no way to debug it. Therefore, it's
+ unlikely that I'll be able to fix this problem myself; but if you
+ have the equipment and skill to do so, I'd be interested in
+ receiving a patch.</li>
+
<li>The re-scan feature occasionally produces odd results, such as
ignoring new media or keeping old media that have been ejected.
This should be investigated and fixed.</li>
<li>The code is in need of review to search for memory leaks and
similar problems.</li>
+ <li>If the user has a Linux software RAID 1 array, rEFInd will detect
+ kernels or boot loaders in RAID 1 twice. This could be fixed by
+ adding a check for duplicate filesystem UUIDs to the
+ partition-scanning code.</li>
+
+ <li>Some Macs experience problems with waking up from suspend states
+ when rEFInd is installed. Unfortunately, I lack the hardware to
+ test and experiment with this (my only Intel-based Mac doesn't
+ exhibit this problem), so I can't fix this myself. <a

</ul></li> <!-- Known bugs -->
<li><b>New features I'd like to add:</b>
loader settings—say, to disable one specific boot loader or
change its icon.</li>
- <li>A way to set the color of the font would be useful for theming
- purposes.</li>
-
- <li>Going further, the ability to load arbitrary other fonts, ideally
- in a standard format, would be desirable for theming purposes.</li>
+ <li>The ability to rotate the display for users who rotate their

<li>A GUI configuration tool would be nice, but it's low on my personal
priority list. If you'd like to contribute, I prefer something
<ul>
- <li>Drivers for additional filesystems are desirable. Given the talk of
- shifting to Btrfs, that should be the priority; however, other
- Linux filesystems, UDF, and perhaps others would all be welcome
- additions. Also along these lines, adding drivers for Linux LVM and
- RAID setups would be useful, too.</li>
-
- <li>As detailed on the <a href="drivers.html">drivers page,</a> there
- are performance issues with the drivers on some systems. I suspect
- that most "real" computers aren't greatly affected (in my tests,
- the problem is worst with VirtualBox, and the next worst is a
- system that uses <a
- href="http://www.rodsbooks.com/bios2uefi/">DUET</a>). Nonetheless,
- I'd like to track down the cause and fix it.</li>
+ <li>Drivers for additional filesystems are desirable. Only XFS and JFS
+ are missing from the major Linux filesystems. UDF would also be a
+ welcome addition, as might drivers for other OSes (say, for the
+ BSDs, especially if BSD developers create a boot loader similar to
+ Linux's EFI stub loader). Also along these lines, adding drivers
+ for Linux LVM and RAID setups would be useful.</li>
<li>The HFS+ driver returns a volume label of "HFS+ volume", no matter
what the volume's real label is.</li>
</ul></li> <!-- Drivers -->
+<li><b>Improvements to <tt>gptsync</tt>, <tt>install.sh</tt>, or other
+ support tools:</b>
+
+ <ul>
+
+ <li>The <tt>gptsync</tt> program can return misleading error codes
+ under some circumstances, such as when it makes no changes to the
+ partition table. Fix this.</li>
+
+ <li>When updating a system with Secure Boot via an RPM or Debian
+ package, the RPM installation script can detect rEFInd's existing
+ shim or PreLoader program and pass options to <tt>install.sh</tt>
+ to try to copy these programs over themselves. This results in a
+ message that the copy was over the same file and an error message
+ that there were problems with the installation, although this isn't
+ really the case.</li>
+
+ <li>A Mac-specific package is highly desirable.</li>
+
+ </ul></li>
