[desktop-discuss] Re: gnome-session crash

[Yasuhiro Fujitsuki]

Hi, 

I have tested diskless client environemnts. My workaround is as follows.

Change server's dfstab as follows.

# cat /etc/dfs/dfstab
# share -F nfs -o ro /export/exec/Solaris_10_i386.all/usr
share -F nfs -o rw=w1100z,root=w1100z /export/exec/Solaris_10_i386.all/usr
share -F nfs -o rw=w1100z,root=w1100z /export/root/w1100z
share -F nfs -o rw=w1100z,root=w1100z /export/swap/w1100z

fc-cache seems to make font information files, fonts.cache-1 and so on, 
at the first time of the login Gnome desktop(JDS) only.
So, after login, it seems no problems to change /usr to read only. 

thanks,

yasuhiro(thaniwa)
