Hi Doug

This is bad=2E It did not work for me that way either on the / partition=2C=
 but=20
it worked on the other partitions=2E
Because I have seperate /tmp /var and /usr partition I was able to mount th=
e=20
/ partition readonly in multiuser mode with mount -o ro / and then tunefs -=
j=20
disable and right after that reboot=2E
It seems that somehow when the / partition gets mounted after disabling the=
=20
journal=2C journaled soft updates is still set and thus still enabled=2C bu=
t=20
with a reboot it gets cleared=3F
I don=27t really understand this=2E
