Hi,

I'm maintaining TI-RPC tests in LTP [1] (ugly, buggy, not covering much from
TI-RPC and should be rewritten from scratch, but I just scratched a surface).
While debugging some of the problems with Steve [2] I found that there are
problems using certain functionality on netns. Not sure if anybody cares about
bug fixing of the glibc implementation, I'd personally prefer the development
moved to libtirpc and rpcsvc-proto. But agree all this might not be a good
reason.

Thanks!

error: xfopen.c:29: could not open /etc/ld.so.conf (mode "a+"): No such file or directory
error: 1 test failures

OK, I'll try to run ldconfig.
Sorry for missing obvious problems.

Thanks a lot! Previously I looked at https://sourceware.org/glibc/wiki/Testing/Testsuite

Kind regards,
