Well, there's a /scratchbox/users/hendrik now.

Ouch.

I seem to off track now.  Things are not behaving as I expect from the
 instructions.  Running the next commend in the list gives me:

hendrik at lovesong:~$ sb-conf rs mistral-armel /scratchbox/packages/mistral-armel-rootstrap.tgz

You dont have active target in scratchbox chroot.
Please create one by running "sb-menu" before continuing

sb-conf: No such target: mistral-armel
sbrsh-conf: No current target
hendrik at lovesong:~$


And sb-menu gives me a lot of choices without explaining what they mean.
What, for example, is a target?  If 'mistral', 'bora', and 'chinook' are
targets, isn't setting them up what these instructions I'm following are
supposed to do?  It looks as if things have changed since these
instructions were written, or else that my installation has been
derailed somehow and I should wipe it and start over, with a different
debconf priority.

I feel like I'minstalling slackware again, but without the handy few
pages of paper telling me what's going on.  Is there documentation
somewhere that could tell me what's going on behimnd the scenes? -- what
all these commands do and need to do?

I'm running lenny with its up-to-date kernel.  Thanks for warning me
what's coming,

Do these have to be reentered every time I reboot?
