Ok, that's fine (I remember my last CF card dying in a LinVDR[1] box writing 
hours and hours of TV to a failed NFS mounted directory ;-) ... but I really 
do try to understand why. What does the following tell me?

-------- 8< --------
# cat /etc/fstab
/dev/hda1       /       ext2    defaults,noatime,rw     0       0
proc            /proc   proc    defaults                0       0
tmpfs           /rw     tmpfs   defaults,size=8M        0       0


# mount
rootfs on / type rootfs (rw)
/dev/root on / type ext2 (ro,noatime,nogrpid)
proc on /proc type proc (rw,nodiratime)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw)
tmpfs on /dev/shm type tmpfs (rw)
tmpfs on /rw type tmpfs (rw)

What is /ro/* used for? There is not even one match searching for it 
in /etc/*.

I have no other machine available here, so logging to ramdisk sounds good as 
long as there is a cron job for eaxample that writes its contents somewhere 
else when free space falls below a defined value (2 MB). 


Thanks
