iscsitarget (http://iscsitarget.sourceforge.net/) basically works fine, but for 
newer kernels we have to switch from stable branch to develbranch. stgt (see 
http://stgt.berlios.de/) got part of kernel 2.6.20 and therefore we should end 
suport of iscsitarget and provide support for tgt instead (as openSUSE does as 
well:
https://lists.berlios.de/pipermail/stgt-devel/2007-April/000517.html).

Userstuff compiles without any problems (needs libaio-dev), waldi plans to 
provide a debian package as soon as the license issue (see https://
lists.berlios.de/pipermail/stgt-devel/2007-April/000499.html) has been resolved.
