[NFS] some strangeness (at least) with linux-2.4.18-NFS_ALL patch

[Hans-Peter Jansen]

Hey, Howdy, Hey Trond, [forgive me, watched Toy Story 2 dvd today :)]

me again ;-)

I've messed it up, mea culpa. Sorry!

I redid my kernel today, using your 2.4.18-NFS_ALL from last night ;-),
based on 2.4.18-pre3, but kept out Andrea's 00_lowlatency-fixes-4 for 
now:
imon-0.0.2-2.4.12-hp
linux-2.4.18-NFS_ALL.dif
00_nanosleep-5.dif
pnpbios.patch_latest
vmscan.patch.2.4.17.dif
ide.2.4.16.12102001.patch.bz2
bttv-0.7.88-2.4.17
btaudio-2.4.17
and my symlink problem disappeared. I thought, I could reproduce a
longer standing problem, which bites me from time to time.

Here we go:

When it came to the usual lm_sensors 2.6.2 modules install within 
the client, this happened:

Somehow, gcc managed it to create an invalid link in the above sequence.
Really bad is, you cannot get around this within the client. After 
rm'ing lib/libsensors.so.1 on the server, make install succeeds on the client.

[...]
rm -f lib/libsensors.so.1
ln -sfn libsensors.so.1.2.0 lib/libsensors.so.1
mkdir -p /usr/lib /usr/include/sensors /usr/man/man3 /usr/man/man5
install -o root -g root -m 644 lib/libsensors.a lib/libsensors.so.1.2.0 
lib/libsensors.so.1 lib/libsensors.so /usr/lib
ln -sfn libsensors.so.1.2.0 /usr/lib/libsensors.so.1
ln -sfn libsensors.so.1 /usr/lib/libsensors.so
[...]

I can reproduce this now. Do you?

Hope, I don't bother you above the critical mass, because I don't want
to trigger the third world war, in case you get out of control and explode
unconditionally. Warn me in time plz :)

Happy NFSing'ly yours,
