Portsnap only updates the ports tree (the directories under /usr/ports),
not the installed ports themselves. You'll need either
/usr/ports/ports-mgmt/portupgrade or /usr/ports/ports-mgmt/portmaster to
keep installed ports up to date. I prefer portmaster since it doesn't
depend on a separate database as portupgrade does. Depending on how long
it has been since you've updated your ports and the speed of your
machine, updates can indeed take a long time. You could choose to use
pre-built packages instead of compiling from source, to speed things up.

Did you check that the GENERIC kernel that you built was installed as

It is unclear to me why you should have to reboot to transfer
files... If you want to e.g. connect two machines with an ethernet
cable, are you aware that you can use the scripts in /etc/rc.d to stop
and restart networking?
And why not just transfer files with a USB thumbdrive?

Without a more thorough description of the steps that you followed,
there is not really a lot others can do to help you. From your
description it is totally unclear what has gone wrong.

Type ? at the boot prompt to see a list of files in the root directory
of the default boot device. Read the boot(8) manual page.
It could be that something went wrong with your disk. Mabye the slices
or partitions were deleted.

Does this configuration file (see above) exist?

If you want a custom kernel, I find it more convenient to upgrade from

A custom kernel will save some boot time because it doesn't probe for
devices that aren't built-in or loaded as modules.
There are some things (options) in the kernel that you cannot load as modules,
they need to be compiled in. E.g. the scheduler, or if you want to use
device polling instead of interrupts. See e.g. /sys/i386/conf/NOTES for
options and devices that are not part of the GENERIC kernel.

I don't think you have to reinstall all programs. Just restore
/usr/local and /var/db/pkg from backup. You did make a full backup
before trying to upgrade, I hope? If not, I trust you remember to do so
in the future...
Contrary to what the handbook says, you do not always have to reinstall
all ports when updating the system. It is definitely necessary when
updating to another major version (6.x -> 7.x), but when updating to
another minor version (7.1 -> 7.2) it is usually not necessary (unless
/usr/src/UPDATING says differently).

Not to put too fine a point on it, but that is why you should make
regular backups of all your important data.
