+2.10.0 cannot be installed on case-insensitive file system
+
+The https://download.qemu.org/qemu-2.10.0.tar.bz2 tarball cannot be unpacked on a case-insensitive file system because it has a file qemu-2.10.0/roms/u-boot/scripts/Kconfig and a directory qemu-2.10.0/roms/u-boot/scripts/kconfig. This prevents installation on most macOS systems since by default the file system is case insensitive. The 2.10.0 upgrade is blocked in Homebrew due to this issue. See https://github.com/Homebrew/homebrew-core/pull/17467. This is a regression from 2.9.0, which didn't have this problem.
+
+That's apparently a problem with U-Boot. Could you please report this issue to the U-Boot project instead (see https://github.com/u-boot/u-boot)? We only include the u-boot sources in the QEMU tarballs, but we do not maintain them in the QEMU project, so we can not fix this issue here for you, sorry.
+
+The offending commit is https://github.com/u-boot/u-boot/commit/61304dbec36dc445bbe7d2c19b4da0695861e0a8 so it should be possible to downgrade u-boot until it gets fixed upstream, no?
+
+I don't think it would be wise to downgrade u-boot. You can always just skip unpacking the u-boot sources -- we don't actually build them, we just ship them for license compliance reasons.
+
+
+Hmm I'll try some magic tar invocations.
+
+>we don't actually build them, we just ship them for license compliance reasons.
+
+Would you be in compliance with the license if the u-boot sources were themselves in a tarball inside your qemu tarball?
+
+Yes, but that's not how we ship them today. (We're actually considering having the ROM blob sources be in an entirely separate tarball from the QEMU sources, for unrelated reasons).
+
+We should fix this bug by:
+ (1) getting u-boot to fix it upstream
+ (2) moving to a fixed u-boot
+
+
+I agree. But it's not really tenable in the interim for the 2.9.0 tarball not to be able to even be unpacked on macOS.
+
+There is a simple workaround: use
+  tar xf qemu-2.10.0.tar.xz --exclude qemu-2.10.0/roms/u-boot/scripts/Kconfig
+
+
+Right. The issue is that solution is O(n) not O(1).
+
+Eh? That command line is not particularly slow, especially compared to the time it takes to download the tarball in the first place.
+
+
+I mean in that every user is going to have to figure this out individually until it's fixed.
+
+In any case it will not be a problem for our Homebrew users, as I will do this:

+
+Yes, it's awkward for users who are on OSX (or Windows, I assume). But the 2.10.0 release is already out and we can't change it -- if this bug had been reported for one of the 2.10.x release candidates it would maybe have been a release blocker. As it is we have to wait for a 2.10.1 release (and we need to actually fix the problem, preferably by getting u-boot upstream to do so).
+
+Thanks for putting the workaround into the homebrew packaging in the meantime.

+>Thanks for putting the workaround into the homebrew packaging in the meantime.
+
+You're welcome. I have now shipped the 2.10.0 binaries.
+
+>if this bug had been reported for one of the 2.10.x release candidates it would maybe have been a release blocker
+
+We should add a `devel` spec to the qemu formula for the next release candidates. I will try to remember.
+
+> As it is we have to wait for a 2.10.1 release
+
+Yeah that is unfortunate.
+
+>(and we need to actually fix the problem, preferably by getting u-boot upstream to do so).
+
+Agreed. If only their mailing list would confirm my subscription ... lol
+
+
+See https://lists.denx.de/pipermail/u-boot/2017-September/304728.html.
+
+Thanks for taking care of that @ubuntu-weilnetz
+
+Update: Sam Protsenko has kindly written and submitted a u-boot patch which resolves the filename clash:
+https://lists.denx.de/pipermail/u-boot/2017-September/307910.html
+
+
+Hurray!
+
+Somebody re-reported this which reminded me that we forgot to tidy up the loose ends here.
+Current status:
+ * this is fixed in upstream u-boot with their commit 610eec7f0593574 (committed October 2017, and in u-boot release v2017.11 and later)
+ * in QEMU's release process we put in a workaround in our commit d0dead3b6df7f6cd97 which puts the u-boot sources in their own tarball rather than extracted; this went into QEMU release 2.11.0
+ * we are still shipping the same old version of u-boot we were in 2.10
+
+So ideally we'd finish fixing this bug report by:
+ * updating our u-boot to some version v2017.11 or later
+ * removing the d0dead3b6df7f6cd97 workaround
+
+
+We updated our u-boot sources to v2019.01 in QEMU commit f2a3b549e357041f86d7e, and we removed the scripts/make-release workaround in commit 082c0543baa6f23770, so all the loose ends I mentioned in comment #18 are now fixed and will be in QEMU 4.0.
