Solved rsync on FreeBSD Live-CD - possible?

[Marched]

Hello.

I have virtual drive with UFS partitions, I need to boot Live-CD and use rsync to COPY files from remote server to this virtual HDD ("clone" the system). I want to boot from this virtual HDD (I'm using Virtualbox).
So the only one obstacle is that none of the .iso-files (*dvd1.iso and so on) contain the key part: rsync. I can try to use dump/restore but is there a way to INSTALL software to Live system?

dhclient em0
mkdir /tmp/etc
mount_unionfs /tmp/etc /etc
echo "nameserver 8.8.8.8" >> /tmp/etc/resolv.conf
ee /etc/ssh/sshd_config
"#PermitRootLogin no" -> "PermitRootLogin yes"
/etc/rc.d/sshd onestart

SSH works, but I need rsync....

Does pkg install rsync not work?

If not try downloading http://pkg.freebsd.org/freebsd:10:x86:64/latest/All/rsync-3.1.2_1.txz (assuming you use FreeBSD 10/amd64) and just extracting it manually in a location you can write to e.g. /tmp. rsync would be in /tmp/usr/local/bin/rsync then. It has no extra dependencies, so this should work fine.

No, because FS is R/O. But you are genius. I've downloaded the package, extracted and mounted it:
mount_unionfs /tmp/usr /usr. Looks like it works. I will run some test later. Thank you!

From the mount_unionfs(8) man page:

THIS FILE SYSTEM TYPE IS NOT YET FULLY SUPPORTED (READ: IT DOESN'T WORK)
AND USING IT MAY, IN FACT, DESTROY DATA ON YOUR SYSTEM. USE AT YOUR OWN
RISK. BEWARE OF DOG. SLIPPERY WHEN WET. BATTERIES NOT INCLUDED.

I'd say just use dump and restore. The results are the same as using rsync.

Looks good, I've copied all files with dump/restore* and trying to update 7.4 -> 8.4

* like this:
cd /mnt/usr && ssh REMOTESERVER dump -C16 -b64 -0uanL -h0 -f - /usr | restore -ruf -
and so on.
