Here is another problem I got, maybe related to previous one (it also
involves renaming and reiserfs).
This happened on a different machine with SuSE 2.6.13-15.8-default and
unionfs 1.1.4

Hello,
I am trying to create a gentoo system into a chroot unionfs filesystem.
I have the following configuration:
Latest unionfs snapshot from ftp:20060423-1600
localhost ~ # uname -a
Linux localhost 2.6.16-gentoo-r4 #1 SMP Sun Apr 30 04:46:31 EEST 2006
i686 AMD Athlon(tm) XP 2200+ AuthenticAMD GNU/Linux
level1 folder which contains the gentoo stage2 and portage snapshot (RO)
level2 folder on top of it (RW)
mount -t unionfs -o dirs=${LEVEL2PATH}:${LEVEL1PATH}=ro: unionfs ${IMAGE}
Both level1 and level2 are on reiserfs.
The first problem I encountered is a infinite loop in the kernel modules.
It only happened after emerging gcc, when it tried to strip the executables.
When this happened any ls in the executables path both in mounted
image or even in
level2 would freeze.
Here are some consecutive sysrq showRegs output:
i686-pc-linux-g is in fact i686-pc-linux-gnu-strip

When i changed the filesystem from reiserfs to ext3 the problem went away.
The second problem(?) I encountered is that the /tmp folder in level2
gets a lot of .(13000+ and conting) .wh.* files even if in the /tmp
folder in level1 is empty. Is this normal?
