Solaris and Linux on one disk?

Solaris and Linux on one disk?

[Grant Beattie]

Hi all,

Is it possible to have Solaris and Linux reside on the same disk and
multiboot?

Also, does Ultralinux support the UFS file system? Would be nice if
both OS's could share a partition, eg. /export.

thanks

Yes, SILO supports it, but due to missing features in IEEE1275 PROM one
cannot pass arguments to Solaris kernel that way. So one might also want to
install Solaris on a different partition and put it's bootblocks there, then 
boot disk:d or whatever.

Current CVS kernel (see ftp://vger.rutgers.edu/pub/linux/README.CVS) has
read-write support for UFS, although it is still experimental. So, don't use
it for data you would not like to loose. On the other side, bug
reports/comments are welcome and may improve UFS support, so that it moves
from EXPERIMENTAL to stable...

Cheers,

yes.

Very important : See the Silo readme in /usr/doc the boot partitions of both
Solaris and Linux must be on the same first 1Go of the disk. because there is
a bug in eprom.
So you must have 
/dev/sda1 450mo -> solaris /
/dev/sda2 450mo -> linux /
/dev/sda3 xxxxMo -> solaris /usr
/dev/sdaYY xxxxMo -> solaris or linux  /usr local home or other

install solaris first, and ask for a second partition /linux than install
linux : reformat this partition and install it.
than configure silo

No problem :

mount -t ufs /dev/sdxx /export

I'd be glad to play around with it if it will help improve stability.
I have a Sparc 5/170, any good or bad experiences with these?

I use SunOS 4.1.2, Solaris 2.4 and Linux on both an IPC and a SS2.
I use the following configuration for /etc/silo.conf:

------->snip<-----
timeoutP
partition=5
root=/dev/sda5
image=/boot/vmlinux-2.0.27.gz
        label=linux
        root=/dev/sda5
        read-only
image=/boot/vmlinux-2.0.32.gz
        label=lin32
        root=/dev/sda5
        read-only
image=1/kernel/unix
        label=sol
        solaris
image=1/kernel/unix
        label=sol-single
        literal="-s"
        solaris
image=1/kernel/unix
        label=sol-conf
        literal="-r"
        solaris
other=4
        label=sun
image=sd()1/kernel/unix
        label=sol-ipc
        solaris
other=sd()4
        label=sun-ipc
------->snip<-----

One word to the mixed bootprom V0 and V2 entries.
I have one silo.conf for both machines.
And my IPC has a bootprom V0 whereas my SS2 has V2.
For the linux partition this does not matter but for SunOS and Solaris.

Of course you have to modify it for your needs.

As far as I know UFS is only supported read only.
And there is yet no ext2 support for Solaris.
So both OS's can NOT share a partition except the swap partition.

Hope this helps.
