Something strange happens with apache and livecds/USB

[Antonio.Amorim at sim.fis.fc.ul.pt (Antonio Amorim)]

Hi,
  We had a similar problem in PAIPIX.
Apache2 uses an optimized  sendfile approach that does not work using a 
filesystem over UNIONFS.
This can be fixed  by adding  to /etc/apache2/apache2.conf the statment:

EnableSendfile off

for example after the line:
ServerRoot "/etc/apache2"

All the best,
Antonio Amorim
