Hi,
None of my kernel v2.4 gentoo machines have a /lib/tls directory. Is there
another indication of TLS being used?
My kernel v2.6 machines (non-openmosix) do have /lib/tls, but I think it has
to do with NPTL being used.

on my kernel v2.4 openmosix cluster:
"clusternode:" ldd `which cat`
libc.so.6 => /lib/libc.so.6 (0x4001c000)
/lib/ld-linux.so.2 (0x40000000)

I'll add trying Tab's 2.4.22-om20031215 to my list of troubleshooting steps!
Thanks,
