Can't install FreeBSD-amd64-9.0-RC2: "/mnt: out of inodes"

Hi all,

I tried to install FreeBSD-9.0-RC2-amd64-dvd1.iso (SHA256 verified) on
a VM and meet a reproducible problem:
The VM has 128Mo RAM and a 4Go hard drive.

During install process I choose these distribution sets: ports and src only.
And I'm using guided partitioning / Entire Disk / All Auto

But each time (I delete and re-create a new VM multiple times) the
installer failed during archive extraction of ports.txz (at about 88%
progress of this file extraction) with this message:

Error while extracting ports.txz:
Can't create
'usr/ports/databases/p5-DBIx-Sunny/pkg-plist'

And on the background there is this message:
...on /mnt: out of inodes

Can someone else confirm this problem before I fill a PR ?

Regards,

Olivier
