thanks to marco greene for noting that the machines in question need to
be time-sync-ed, in addition to making sure the uid/gids match up, and for
suggesting that i take those users who will be in nis+ out of the /etc/passwd
files entirely; since i'm first just sync-ing the machines without actually
implementing nis+, however, the latter wouldn't be practical just yet.
also of mild interest is the fact that, despite a typo in the url
provided, webserver logs here show 17 non-local addresses accessing the perl
script i posted; i received no actual comments on the script, however. i've
made some more changes and actually tested the migration on my entire fs (on a
non-produciton box, of course) over the weekend, and everything went fine. i've
got some ideas for improving the script (having it automatically update
/etc/passwd and /etc/group, and better integrity checks before starting the
actual migration, to name the two big ones); since a fair number of people
showed some interest in the script itself, i'll probably keep updating that web
page (<http://astaroth.nit.gwu.edu/~sweth/geek/mvid.html> is the correct
url--note the single a at the beginning of astaroth), and if people want to send
me an email, i'll send one back with the final version of the script, once i
think it's ready enough for distribution to the coworkers of mine who will have
to sync up the other machines here.
