unionfs in livecd?

At least in 6.2-BETA the original unionfs leads to random locks
for disk-based partitions. I can reproduce it in 15-30 minutes of
using unionfs-mounted filesystem.

The unionfs patchsets from Daichi Goto are very good, at least for
me: I've not expirienced any lockups since 6.1. So, you probably should
give it a try.

My usage of unionfs-mounted filesystems is connected with sequentially
serving large data transfers (about 2 Gb in a couple of minutes)
to a moderate number of clients (aroung 100). These transfers are
not frequent, but as they go they can produce a huge load spike to
a server's filesystem. Such spikes are definitely locking up the
filesystem with the original unionfs.
