/usr/bin/uname -s
AIX

And depending on your version needs

/usr/bin/uname -vr
3 5 (version 5 release 3 in reverse)

/usr/bin/oslevel -r
5300-05

/usr/bin/oslevel -s
5300-05-03

Confused a bit on how you intend to boot the AIX image.
Can you explain further?

Yeah sure. I guess my initial post wasn't all that clear. Let us
suppose I have a Sun or Linux boot server and I have a set of ramfs for
AIX, SunOS etc. which will be tftp-d to the remote machines. These
remote boxes can then boot using the ramfs and some bootloader which
reads from their network interfaces.

Once I have booted the kernel however, I might need to run a small
shell and access some basic utilities. I might want at least a small
read-only file system from which I can do all this. Our filesets
provide this facility. Once my remote box boots into AIX from the ramfs
my server provides, the remote machine can NFS-mount this file set from
my server and run commands. Further, I can put custom executables in
this fileset - so the remote machine can run some special commands
which I have provided. So, I don't really boot from this fileset - I
merely mount it and use it after boot.

Now that means - on the boot server, this fileset is merely a set of
files and not a live system on which commands can be run. So I cannot
run something like uname there. So I was wondering if I could check out
some filesystem entries or read some config file to be sure that this
is actually a Solaris fileset or an AIX fileset, of so and so version
and running on this or that architecture.
