After having setup a system with UEFI, I have a few questions: 1. Why is the 2MB BIOS partition needed as it is not formatted? Does GRUB actually install itself here? 2. The EFI partition need only contain GRUB files (including the grub.cfg which tells GRUB how to boot an OS). 3. If I were to boot a system without EFI support, the 2MB partition should kick in and GRUB would still read the grub.cfg on the EFI partition? Is that accurate? So, when installing GRUB with the EFI options, does it still setup the MBR part? Thanks, Walter

If I want to build a custom debian kernel, am I correct in my understanding that I would want to use: -binary +luks for my use flags? If so, it appears the ebuild won't let me do it. If I'm not worried about building unnecessary modules and features into the kernel, then, I can just call it a day by adding the luks use flag and defaulting to binary?

@drobbins Thanks for the information - I will make the switch now. Thanks, Walter

Hi - has there been any update to updating gentoo-sources in 1.4? I use gentoo-sources. What is the advantage of debian-sources over gentoo-sources, stability, security? What is the advantage of gentoo-sources over debian-sources, speed? Thanks, Walter

I have been using bootable USB thumbdrives for sometime and had recently attempted to boot to it to find that I cannot. I get a kernel panic: trap invalid opcode ip: ... error:0 in ld-2.29.so When I boot the same thing but from my local disk, I can boot ok. The USB thumbdrive contains a nearly identical boot: same kernel same init different grub.cfg (different UUID for device) Root is on a LUKS partition with LVM for both USB and local disk. Root is a squashfs image. I am using overlayfs to make root writable. The system I was booting on was different from my build system and I recently changed the sub-architecture I'm using. I have another configuration which specifically targets that architecture, so I need to use that instead. Walter

Ah, you're right, my chromium build fails and isn't cleaned up. I will modify the build process to wipe /var/tmp for me :). I was checking after the entire build completed and /var/tmp was wiped - I forgot about failed builds not being cleaned.

I am attempting to install git-annex and apparently this has not been installed for some time, but I did have git-annex installed a while back. My /var/tmp is tmpfs and has 12G allocated. When attempting to install git-annex, it requires at least 8GB free and fails: Checking for at least 8 GiB disk space at "/var/tmp/portage/dev-lang/ghc-8.0.2/temp The build will most probably fail, you should enhance the space as per failed tests. I could do a bind mount here, but why does the ebuild care if it is disk or memory for the underlying device? Is there another way around this short of doing a bind mount here? Thanks, Walter

The build failed here now: /usr/include/glib-2.0/glib/gtypes.h:549:26: note: declared here 549 | typedef struct _GTimeVal GTimeVal GLIB_DEPRECATED_TYPE_IN_2_62_FOR(GDateTime); | ^~~~~~~~ cc1plus: all warnings being treated as errors cc1plus: all warnings being treated as errors cc1plus: all warnings being treated as errors > Task :graphics:ccLinuxGlassGlassgtk2 FAILED :graphics:ccLinuxGlassGlassgtk2 (Thread[Task worker for ':' Thread 2,5,main]) completed.

Changing the ebuild to also check for that directory got my swt installation moving along ... Shall I clone the repo in git, then open an MR? Walter

When I launch nestopia, I get an immediate segfault: nestopia[5264]: segfault at 10 ip 00007fe24e3e9e74 sp 00007ffc936c9e40 error 4 in libgcc_s.so.1[7fe24e3dc000+11000] [83739.944349] Code: ff ff c5 f8 29 9d 00 ff ff ff c5 f9 6f 95 80 fe ff ff c5 f9 6f 9d 90 fe ff ff c5 f8 29 a5 10 ff ff ff c5 f9 6f a5 a0 fe ff ff <49> 83 7c 24 10 00 c5 f8 29 ad 20 ff ff ff c5 f9 6f ad b0 fe ff ff I'm wondering if anyone else has it running or recommends another emulator.

Thanks all, the issue is solved!

Thanks, for catching that. I'll make those changes and report back. My make.conf is automatically generated by a utility ... that said I am no longer writing empty values (such as VIDEO_CARD=""), but instead have this: HOST="x86_64-pc-linux-gnu" CFLAGS="-march=ivybridge -O2 -pipe" CXXFLAGS="${CFLAGS}" CPU_FLAGS_X86="aes avx mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" MAKEOPTS="-j5" # patches below here # kernel USE="${USE} symlink -fortran -openmp acpi" The other changes I made were: ->=x11-base/xorg-server-1.17.4-r2 xvfb +#>=x11-base/xorg-server-1.17.4-r2 xvfb -media-libs/mesa bindist -gallium -d3d9 -llvm -x11-base/xorg-server glamor glvnd udev +#media-libs/mesa bindist -gallium -d3d9 -llvm +#x11-base/xorg-server glamor glvnd udev

When playing a video, I noticed that I apparently am lacking opengl acceleration as the video plays terribly slowly. My package use flags: media-libs/mesa bindist -gallium -d3d9 -llvm x11-base/xorg-server glamor glvnd udev Part of my make.conf CHOST="x86_64-pc-linux-gnu" CFLAGS="-march=ivybridge -O2 -pipe" CXXFLAGS="${CFLAGS}" CPU_FLAGS_X86="aes avx mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" MAKEOPTS="-j5" USE="opengl X xinerama dbus gtk gtk3 -gnome-keyring" VIDEO_CARDS="" SANE_BACKENDS="" LINGUAS="" I have the gfxcard-intel mix-in enabled, so my VIDEO_CARDS should be set to all intel. Additionally, I have followed the guide here to my knowledge and have installed libva-intel-driver: https://www.funtoo.org/Make.conf/VIDEO_CARDS/Mix-ins. Is there something else I'm missing? This was working fine on 1.3 and I believe I had manually set the VIDEO_CARDS setting then as there may not have been a mix-in.

I must have had an old kernel built, so the kernel source directory was not configured properly.
