More importantly, which ISA/ARCH is it based on.
He forgot to mention that most important piece of information.
It must have been sparc, because sparc doesn't use grub so far.
To boot Grub based "newboot" flavours of Solaris x86/x64 (and therefore
2.10_U1 or higher, or 2.11_b15(circa) or higher) with only 64MB of
physical mem, one needed to have a _very_ small custimozed boot archive.
See Moinak Ghosh's good work to shrink that down beyond the limits.
(The boot archive is pre-(down)-loaded and must completely fit into ram.)
I doubt DC has worked on that.
It can only be sparc because of that.
Likely you are right.
I wonder if we could do the trick similar to what Linux kernel is doing
with initrd? i.e. free up ram disk space for applications after kernel
is initialized and HDD root is mounted.
There are more possibilities in this area. I am looking at replacing
/sbin/init with a
shell script that mounts the CDROM first and then execs the real
init. This will allow
putting most of the /lib and /sbin and others onto CD. If I use bash
as the shell, then
only libc and libm need to be present on the ramdisk in /lib.
So the size of the ramdisk should be reduced by around 28MB (from 62
to 34).
An additional possibility is to port UnionFS from FreeBSD (+patches)
which should
allow more kernel modules to be moved onto CD.
However all these might impact bootup performance a bit.

Moinak.
