Yes. Because we can burn them to DVD for read-only optical and we can use 2=
GB, 4GB, or greater-sized USB Thumbs.

@ $work we've been able to keep the size of the ISOs down by using sysinsta=
ll from an mfsroot.

=3D=3D=3D

ASIDE: I recently analyzed what we would need to put bsdinstall+bsdconfig i=
nto an mfsroot to do similar things as sysinstall...

(sorted alphabetically)
/bin/sh /usr/sbin/pkg_add* awk bsdlabel** cat cdcontrol chmod chown cksum c=

sfs=20
mount_nfs moused mv nc pkg_delete* pw rm route rtsol sed sleep sort stat st=

sysctl tail tr umount uname vidcontrol

(optional functionality requirements; not required in mfsroot)
Xdialog logger su sudo touch xauth xterm

* bsdconfig(8) yet to be updated for pkg (for configPackages)
** bsdconfig(8) yet to be updated to use gpart to probe for disks (for medi=
aSet*)

=3D=3D=3D

Despite the fact that what we've only published builds under 600MB, in-hous=
e @ $work, I've made so-called "super discs" that contain multiple arches +=
 multiple releases. For example, I once made a multi-GB DVD that contained =
4.11, 8.1-32, 8.1-64, 8.3-32, 8.3-64, 9.0-32, and 9.0-64 (plus several util=
ities like memtest86, memtest86+, memtest86+SMP, windiag, Derik's Boot-And-=
Nuke, TuffTest Pro, SpinRite, WD Velociraptor FW updates, Seagate SeaTools =
(both GUI and Txt version), and yet even more. I think the resulting ISO wa=
s about 2.7GB. It fit nicely on a 3GB thumb-drive I had and it burned well =
to DVD. It was very nice being able to walk around with one disc or one thu=
mb drive and be prepared for anything/everything.

(I carry one one me at all times in my coat pocket ^_^)

So yeah... >700MB shouldn't be a problem.
