No issues.
There are 'no issues' per se.

While we are on the subject.....

I rarely (if ever) install multiple OS on a single disk because it is only possible to run one OS at a time. All my servers are up all the time so there is not reason to be NT one day, Linux the next, and Solaris86 another day (because they are in production use). Lab and classroom use is different, BTW.

Many people who like to learn 'one at a time' (in student or lab mode) do the 'multiple boot OS thing'; but with computers so cheap, disk space & CPUs almost free, I prefer to have multiple platforms vs. multiple bootable partitions.

However, if you are in class and just loading different OS to study then the installation is straight forward. If you are going to build cross-platform utilities, I suggest you install the GCC development environment so you can build binaries to run independent of vendor compiler.

installboot

installboot(1M)                                                                                                                    installboot(1M)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk         The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
                       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

              example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
                   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

           directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
