[OpenIndiana-discuss] problem config grub permanent

[Heiko L.]

hallo,

I have a problem to configure grub on openindiana
I write a new entry into menu.lst (outside BOOTADM,LIBBE)
After reboot, the changes are overwritten.

Whats going wrong?

Who change this entry?
menu.lst seen to overwrite by bootadm on each reboot,
but I could not find the source.

Regards Heiko
