Title:
Linux fails to read GPT(EFI) partition table created by both GNU
parted and OSX diskutil
To
Results of testing on Mac:
* parted do not create MBR when empty GPT is created.
* ubiquity:
a) When starting from empty GPT and creating partitions on GPT it creates
synced MBR, but Linux then reads MBR instead of GPT.
b) Created by ubiquity partitions created without alignment.
I can't think of any authoritative contact.
Anyway, If existence of MBR (at least protective MBR) is vital part of GPT/EFI
specification then it's ok for Linux to demand it.
Linux could just ignore absence of MBR in GPT, but we can't treat its behavior
as bug.

Linux fails to read GPT(EFI)
Reconstructed the problem (with parted 2.2-1ubuntu2):
1. Clean GPT with 3 partitions (Gparted)
2. Start ubiquity (Lucid Daily)
* Change type of 3rd partition
* Format 2st and 3rd partitions (ext4 and swap)
* Finish install
3. After reboot found partition table in state as below:

That's a grub-installer bug. Fixed and uploaded, pending release team
approval.
Is there still a bug to handle against linux here? I don't think
there's been any clear identification of a kernel bug, aside from the
question of GPT labels without protective MBRs which I think I addressed

I assume updated parted and grub-installer are still expected to handle Mac

After they will land in Daily Lucid, I'll test them on Mac and report.
About Linux, since Linux supports only Hibryd GPT, we would expect every
partitionnig tool to prepare such, right?

Yes, should do.

Thanks.
About Linux, since Linux
I have tested GPT on non Mac system (VirtualBox).
1) Used gparted LiveCD to create GPT with 4 partitions. As result MBR contained
protective MBR with single partition covering whole suface.
2) Booted in to latest Daily Lucid. Instructed installer to change type of 1 of
4 partitions and use 3 of
Notice how the other bug I referenced is already targeted to beta-1 :-)

Hope issue will be solved soon.
Since my Laptop is currently OS-less (at least for now) I am able to perform
some testing if required.

Indeed, I'm working on it.
On bare GPT volumes: the EFI specification requires that all GPT disks
have a Protective MBR in the first LBA. I think Linux is entitled to
check for this, if nothing else to avoid accidental misdetection of the
partition table format.

Linux fails to read GPT(EFI)
I'd appreciate logs from the non-Mac case (specifically
/var/log/installer/syslog and /var/log/installer/partman). I haven't
been able to reproduce this behaviour in an isolated test of parted, and
I'd like to see the sequence of operations that the installer is
performing.

Eugene,
It may be necessary to run 'sudo apt-get install apport' I had another user
experience issue with apport today and running the install seems to have sorted
him.
Thanks!

Linux fails to read GPT(EFI) partition
Jeremy: What do you mean by install? In case you mean finish install and
then report from fresh installation, then it's impossible since system
may not be formatted...
Apport is still broken in latest daily ISO.
It crashes with python errors in parsing urls or something (under user and
root).
I think I've localized the problem.
Looks Linux unable to deal with GPT pure partition tables (without synced MBR).
In past a patch (gptsync.patch) was added to parted to solve that issue. (Not
sure ubiquity should enjoy from that fix also)
But it looks like parted refuses to sync GPT and MBR,

It's not out of the question that this is actually a parted bug. I
merged the Apple gptsync patch up to 2.2 more or less blindly, and I
could have broken something.
I think you're analysing this incorrectly, though. What I'm seeing in
the kernel is that you need a valid *protective* MBR, as

Colin: Thanks for prompt respond.
Additional testing showed that problem is more severe then I assumed initially.
Testcase:
1) Zero HDD header.
2) Format HDD using OSX installer (3 partitions: fa...@efi-boot, h...@osx,
fa...@linux).
3) Reboot into OSX, partition table looks perfect.
3) Reboot

I must mention that I am using Lucid daily AMD64 ISO for testing and looks like
apport is currently pretty broken.
What information may be helpful?
Meanwhile I'll attach kern.log.
