There was a post from one of the LFS authors about the changes to do to fix this (it's just changing a couple of options when compiling glibc).
However, since it's using a Gentoo rootfs, either he compiled it himself (and in that case disabling "nptl" USE flag is enough) or it was prebuilt for UML (and in that case, the author should have done this). > Alternatives could be: > - using a statically bound init (but you will still have problems with > anything else) > - patching your guest kernel with the nptl patches that can be found in > http://www.user-mode-linux.org/~blaisorblade/patches/devel-guest/uml-2.6.13 >-rc3-git-bb-20050731-19:08/ > Using the latter method I had some success, but the init process is > somewhat unstable (sometimes I get segmentation faults, sometimes not), > and even if the system seems to be stable most of the time it seems that > daemons do not really work.
