>Environment:
	<The following information is extracted from your kernel. Please>
	<append output of "ldd", "ident" where relevant (multiple lines).>
System:	NetBSD 4.99.9 (SIN) #0: Mon Jan 22 14:14:52 CET 2007

Architecture: i386
Machine: i386
>Description:
I have a netbooted machine running netbsd-current-20070121. There is no
local harddrive, all filesystems are nfs mounted. Some linux applications
crash:
	openoffice2-bin: missing vcl resource ...
	firefox2-bin: silent death

From ktrace/ktruss with openoffice it looks like something is wrong with
getdents64. 

>How-To-Repeat:
mount /usr/pkg via nfs v3 and try to run soffice.

>Fix:
use a local installation or an nfs v2 mount.

 I think you want to look at the -X option of mount_nfs(8).

 Thank's, -X helps to run soffice. But I still have problems with
 firefox2-bin. It runs ok, but it fails when I try to install an addon
 (adblock plus).

 The problem is still there. I have about 200 diskless netbsd machines 
 (used as X terminals). There are some application I would like to run 
 local on the X terminal). One of these is skype and it's dumping core on 
 me. mounting -o -X,-2 doesn't help. It happens with
 NetBSD xtk103 5.99.7 NetBSD 5.99.7 (XT) #0: Thu Feb 26 15:49:53 CET 2009
 and with
 NetBSD xtk108 5.0_RC2 NetBSD 5.0_RC2 (XT) #7: Mon Feb 16 14:40:47 CET 2009

 I configured vnd0 to 1.5gb file mounted from the nfs-root, filled it, 
 mounted it and chrooted to it. running skype from there did just work 
 fine, but I think this is just insane.

 Next step: I reverted to nfs and it still runs. It looks like  it just 
 needs to create its configuration files and then it will run...

 Next experiment: It is .fonts.cache-1 which I have to remove to provoke 
 the segmentation fault.

 Regards, Matthias
