Hi,

That will become an adventure. Common roots are more than
20 years in the past.

FreeBSD is not too bad. But you will notice that it has a
much smaller tester community than GNU/Linux. The focus is
on big iron, not on personal computers.

There is a project named PC-BSD which tries to make it more
desktoply:
  http://wiki.pcbsd.org
  http://wiki.pcbsd.org/index.php/Turn_FreeBSD_into_PC-BSD%C2%AE
 

For myself it would not be a good choice, because ISO 9660
mounting cannot handle files >= 4 GiB or multi-session
added above 4 GiB.
Further FreeBSD 8 crashes reliably when i switch off an idle,
not mounted eSATA DVD drive and less reliably when i do this
with a USB DVD drive. (No admin of a 128 core machine would do
that, of course. It could bring bad luck to the 1 TiB of RAM.)

The hardware driver problem might be fixed in FreeBSD 11,
but the ISO 9660 problems are deeply rooted in the code
for inode number generation and inode addressing.

They seem to be heading towards ZFS, due to lack of license
allergic reactions. That will be another culture shock for
a migrant from Linux.
  https://www.freebsd.org/doc/handbook/zfs.html

I know it from Solaris and its administration is very
different from other filesystems. (My favorite command
on Solaris is: pfexec poweroff)

It's that they put several of their "slices" into what we
call "partition".
You typically need one MBR partition to host all slices of
a FreeBSD. That's actually better contained than a Linux
installation. (Dunno how they deal with GPT partitions.)

How about a virtual machine for a start, or Debian/kFreeBSD,
the not so official Debian port to the FreeBSD kernel ?

Everybody should be able to read ISO 9660.
But your mileage varies from operating system to operating system.

I understand the goal was to install FreeBSD so that one can
read (and write ?) its system disk from Linux.
The basic filesystem of FreeBSD is UFS. Seems to be supported
on Linux.
  http://askubuntu.com/questions/85154/mount-ufs-filesystem
I guess it depends aminly on Linux' ability to map slices
to partition devices (e.g. /dev/sdb4).

Yes, it can. (At least with mainstream use cases.)

tar or cpio should be compatible. Not to speak of third party
things like "bru" or "dar". But where to find tape hardware,
anyway ?

I can confirm that DVD with ISO 9660 below the 4 GiB limitations
is exchangeable with Linux. (Unless you hit more bugs of any
of both OSes.)
A DVD with a tape archive on it will work too, of course.
Device addresses are easy: /dev/cd0 , /dev/cd1 , ...

For those who want to develop their own OS entrails:
NetBSD has the nicest kernel developer community i ever met.


Have a nice day :)

Thomas
