Basically I think it did because there were no error messages :-)
But then again, as the respondents unanimously said, my sacrifising
speed and simplicity now is no equal to the pain and grief I might
encounter later because then I would need an identical disk (duuhh,
I forgot about that) and other potential problems.
Anyway, I just used ufsdump 0uf /dev/rmt/0n per raw disk partition
(e.g. ufsdump 0uf /dev/rmt/0n /dev/rdsk/c0t3d0s0). It was more CLI
consuming but only once, during the creation of my script. Of course
I was in single-user mode, but not booting from CDROM 'coz ufsdump
needs to read-write on /etc/dumpdates.
Again, thanks to the wonderful samaritans out there,
Thanks,
Drexx Laggui
