[icecast] YP submission / cURL issue. (icecast 2.0.1 / gentoo)

My chroot shouldv'e been configged quite, nsswitch.conf/resolv.conf/hosts,
and
all libs via the ldd of icecast & bash. What else might one need?

[icecast] YP submission / cURL issue. (icecast 2.0.1 / gentoo)

DNS for vhosts makes total sense, duh! :)

Running without chroot, as root, changing to nobody, and YP works just 
fine.. If
I come up with a nice howto / rundown of the chroot stuff, I'll get it on
the
list.

Odd: Did you see the posts about the Icecast+win32 crashing w/ OddCast 2.0.10
and 2.0.13? Seems stable on 2.0.1-release and SVN on Linux but..

I'm going to do my research and get back in touch.

Do you have an /etc/resolv.conf inside the chroot?  glibc may need that to
figure out where DNS lookups should go, perhaps /etc/nsswitch.conf as well.
You can copy them from the parent host.
