is there no bulk account creation utility on debian for just this
sort of thing? i know i've seen this sort of thing before on fedora,
i just can't remember what it's called.
essentially, you feed the utility a list of lines from an existing
/etc/passwd file, and it runs the appropriate commands to create the
corresponding accounts on a new system. all you need to do is strip a
copy of the /etc/passwd file to the point where it contains only those
users whose UIDs are 1000 and up, since you don't want to touch
anything else.
no such thing? i would have thought that that sort of thing is
*exactly* what you want for migrations.
