Jailing a 4.7 environment on 5.0?
Is is possible to set up a jail that contains 4.7 on a 5.0 system? In particular, how does one deal with the difference between devfs and MAKEDEV? -- Steve To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-current in the body of the message

Your way isn't likely to work now (different device numbers between 5.0 and 4.x) or in the future (future changes to how devices work). Kris msg48578/pgp0.pgp Description: PGP signature

Thanks for the pointer. The entire example doesn't
apply because my /usr/src is FreeBSD 5.0. I have
4.7-disc2.iso and used a md device to copy the files
into a jail. It appears to work, but I have a few more
things to set up. I'll report with a full description
of what I'm doing later.
Um, that's not what I said at all. Just use devfs and be done with
it. Your way isn't likely to work now (different device numbers

work).
You misunderstood. Here's the example again from jail(8).
D=/here/is/the/jail
cd /usr/src
mkdir -p $D
make world DESTDIR=$D
cd etc
make distribution DESTDIR=$D
cd $D/dev
sh MAKEDEV jail
cd $D
ln -sf dev/null kernel
My /usr/src is FreeBSD 5.0. I need a 4.7 environment.
I cannot do steps 2 and 4-8. I did
mkdir /usr/jail
mdconfig -a -t vnode -f 4.7-disc2.iso -u 0
mount /dev/md0 /mnt
cp -pR /mnt/bin /usr/jail
cp -pR /mnt/sbin /usr/jail
cp -pR /mnt/usr /usr/jail
cp -pR /mnt/etc /usr/jail
cp -pR /mnt/var /usr/jail
mkdir /usr/jail/dev
mount -t devfs / /usr/jail/dev
cd /usr/jail
ln -sf dev/null kernel
I'm now ready to configure the jail for my proposes.
What I could not determine from jail(8) was how to
set up /usr/jail/dev. You gave me the pointer to
setting up devfs.
For my application, I need jail/dev/{null,stdin,stdout,
stderr}, gcc 2.9.4, whatever version of binutils is
used on 4.7, and /usr/lib/lib{c,m}.so.X and libgcc.a
