Bug#760148: grub-common: grub-mount hangs forever, trying to mount ext4 partition, causing 100% CPU load

[Johannes Rohr]

Some more strangeness:

I have created the file as instructed, copied /usr/lib* over.

After mounting the file with grub-mount the following happens:

  sudo ls /mnt/testfile/lib/ld*.so
ls: cannot access /mnt/testfile/lib/ld*.so: No such file or directory


But when I specify the full file name, the file is listed:
sudo ls /mnt/testfile/lib/ld-2.19.so
/mnt/testfile/lib/ld-2.19.so

Even sudo ls /mnt/testfile/lib* returns
ls: cannot access /mnt/testfile/lib*: No such file or directory

whereas ls /mnt/testfile/lib without wildcard kind of works (CPU load 
100%, obviously it is at least trying to read the directory contents, 
although I don't see output.

I will upload the file somewhere for your testing pleasure, I'll send 
you a mail when it is available.

Thanks,

Johannes
