[Pkg-libvirt-maintainers] Bug#752107: This seems to be mke2fs' fault

[Hilko Bengen]

control: retitle -1 mke2fs apparently lacks large file support
control: reassign -1 e2fsprogs 1.42.10-1

Here's what went wrong with the latest rebuild attempts for libguestfs
on armhf, mips, mipsel:

1. supermin creates a 4G sparse file
2. supermin tries to create an ext2 filesystem in that file using
   mke2fs -t ext2 -Fq ...
3. Inside mkfs.ext2, opening that file fails with EOVERFLOW ("Value too
   large for defined data type")

I have been able to verify this in a fresh armhf chroot on
harris.debian.org:

$ /sbin/mke2fs -V
mke2fs 1.42.10 (18-May-2014)
        Using EXT2FS Library version 1.42.10
$ truncate -s $((4 * 1024 * 1024 * 1024)) root
$ /sbin/mke2fs -F root
mke2fs 1.42.10 (18-May-2014)
Could not open root: Value too large for defined data type

2^31-1 bytes is the largest file that mke2fs can open.

Cheers,
