In both cases the operation ended normally, no hanging about. It *has* to be something in the kernel. Somehow that SIGPIPE is not getting sent. It doesn't really matter a lot but I am going crazy trying to think of a logical explanation. I asked some of my friends at Linux Forums to try it. So far two have (one with 8.24 on Arch), and both got a normal exit. -- H Russman -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
