Mozilla and NFS -> one system modifies prefs.js

I have already asked this question at netscape.pblic.mozilla.general a half 
week ago, without any reply at all and today I have found this newgroup and 
would try my luck here.

I have got a major problem with my Mozilla (regadles of version since 1.3), I 
have a system where the ~/ is shared over NFS, so the same profile can be 
accessed regadles which machine you are using.

I do use my own ebuild for Gentoo to compile Mozilla, a binary package is 
compiled and then the same version of Mozilla is installed on the other 
machines too. This far everything is okey.

The problem is when using Mozilla,

Senario 1: Mozilla is run on computer A, the 
~/.mozilla/default/lujs3k50.slt/prefs.js stayts at it is.

Senario 2: Mozilla is run on computer B & C, the 
~/.mozilla/default/lujs3k50.slt/prefs.js is stripped on all modifications from 
default settings.

Using user.js don't affect Mozilla, regadles of computer.


I'm really clueless about the difference in behavour, as both machines has the 
same setup and has the same write read premissions on the NFS share, so I 
would really like to have suggestions where to look for things that may cause 
this strange behavour of Mozilla.


This part wasn't included in n.p.m.g:
The following settings disappeares when run on computer B & C
user_pref("browser.chrome.toolbar_style", 0);
user_pref("browser.tabs.loadInBackground", false);
user_pref("browser.tabs.opentabfor.middleclick", false);
user_pref("browser.tabs.opentabfor.urlbar", false);
user_pref("dom.disable_window_flip", true);
user_pref("dom.disable_window_open_feature.status", true);
user_pref("middlemouse.openNewWindow", true);
user_pref("middlemouse.paste", true);

Notes about different computers:
ComputerA: CPU is x86
ComputerB: CPU is x86, Mainly same packages as on ComputerA plus webserver
ComputerC: CPU is PPC, Mainly same packages as on ComputerA plus freevo, uses 
the same ebuild (patches) as ComputerA when building Mozilla.
