Find out OS version and plattform?

[Ede Wolf]

Hi,

is there a way to find out which version of FreeBSD was installed - and 
for what architecture, simply by  mounting the disk?

I am not talking about uname, where you have to be inside the os, but if 
you simply mount the root partition to another computer, where to look 
for these information?

linux has something like /etc/os-release, which is a textfile, is there 
an equivalent [method] in FreeBSD?

grep -ir freebsd /mnt/etc did not reveal anthing, that might give a 
hint. Or I have overlooked this.

Plattform would be more important than version, as latter one may at 
least be guessed by date.

Thanks

Ede
