Setting up boot loader

[martvar]

How can I set up the boot loader to mount
as root filesystem filesystem that is different
than that which is mounted to /boot directory.
Thanks a lot for advise, ...

What platform are you using? On a Sparc platform, you have to install the boot block on the root partition. So if you install one file system on /dev/rdsk/c0t0d0s0 and another one on /dev/rdsk/c0t0d0s6, you will install the boot block on both partition 0 and 6. To select which filesystem you boot your workstation to, you would use:

boot disk0:a "For Partition c0t0d0s0"
boot disk0:f "For Partition c0t0d0s6"

To install the boot block, change directory to: /usr/platform/<workstation platform>/lib/fs/ufs

/usr/sbin/installboot ./bootblk /dev/rdsk/c0t0d0s0 "for partition (a)"

/usr/sbin/installboot ./bootblk /dev/rdsk/c0t0d0s6 "for partition (f)

I'm using x86 platform,
and I want to boot from one partition
e.g. c0t0d0s0 and mount another filesystem
e.g. c0t0d0s6 to root in directory tree.
Someone adviced me to set the root filesystem
in /etc/system file, but how can that file
be used to set the root filesystem when it is a part
of that filesystem and can not be read until
that filesystem is mounted.

I am assuming you are not trying to mount another UFS (Unix File System) as I first thought. To do this:

Create a directory under root:
Example: mkdir mountpoint

Run the mount command:
Example: mount /dev/dsk/c0t0d0s06 /mountpoint

I want to set the bootloader to mount
to root directory / the filesystem
that is different than the filesystem
mounted to /boot directory.
