FreeBSD compatibility with Solaris UFS filesystem?

Hi, I'm new to BSD and would like to create a dual-boot between Solaris Express Community Edition and FreeBSD.

I would just like to know if the Solaris UFS file system can be written to by BSD?

I know that BSD uses UFS2, but I'm hoping that it is backwards compatible with UFS1 provided that Sun haven't or BSD for that matter haven't put any proprietary extensions on the fs.....

Also since I have Debian Linux on my machine right now is it recommended to write to ext3 file system either? I know that ext2 is compatible and I've read that ext3 can be written to but then you don't take advantage of the journal?

Any advice would be great!!

I've tried another forum which told me to use the BSD mailing list, I tried the mailing list and it seems to be dead....?

This is my last chance before either making or breaking the system so I would be ever so grateful for any responses Smilie

Kind regards

UEFI(8) 						    BSD System Manager's Manual 						   UEFI(8)

NAME
UEFI -- Unified Extensible Firmware Interface bootstrapping procedures DESCRIPTION
The UEFI Unified Extensible Firmware Interface provides boot- and run-time services to operating systems. UEFI is a replacement for the legacy BIOS on the i386 and amd64 CPU architectures, and is also used on arm64 and ia64. The UEFI boot process loads system bootstrap code located in an EFI System Partition (ESP). The ESP is a GPT or MBR partition with a spe- cific identifier that contains an msdosfs(5) FAT file system with a specified file hierarchy. Partition Scheme ESP Identifier GPT C12A7328-F81F-11D2-BA4B-00A0C93EC93B MBR 0xEF The UEFI boot process proceeds as follows: 1. UEFI firmware runs at power up and searches for an OS loader in the EFI system partition. The path to the loader may be set by an EFI environment variable. If not set, the default is /EFI/BOOT/BOOTX64.EFI. The default UEFI boot configuration for FreeBSD installs boot1.efi as /EFI/BOOT/BOOTX64.EFI. 2. boot1.efi locates the first partition with the type freebsd-ufs, and from it loads loader.efi. 3. loader.efi loads and boots the kernel, as described in loader(8). The vt(4) system console is automatically selected when booting via UEFI. FILES
/boot/boot1.efi First stage UEFI bootstrap /boot/boot1.efifat msdosfs(5) FAT file system image containing boot1.efi for use by bsdinstall(8) and the bootcode argument to gpart(8). /boot/loader.efi Final stage bootstrap /boot/kernel/kernel default kernel /boot/kernel.old/kernel typical non-default kernel (optional) SEE ALSO
vt(4), msdosfs(5), boot(8), gpart(8) HISTORY
UEFI boot support first appeared in FreeBSD 10.1. AUTHORS
UEFI boot support was developed by Benno Rice <benno@FreeBSD.org>, Ed Maste <emaste@FreeBSD.org>, and Nathan Whitehorn <nwhitehorn@FreeBSD.org>. The FreeBSD Foundation sponsored portions of the work. CAVEATS
EFI environment variables are not supported by loader(8) or the kernel. boot1.efi loads loader.efi from the first FreeBSD-UFS file system it locates, even if it is on a different disk. boot1.efi cannot load loader.efi from a ZFS(8) file system. As a result, UEFI does not support a typical root file system on ZFS configura- tion. BSD
