Thus spake Bernard Li ([EMAIL PROTECTED]):
What we currently do with OSCAR is we truncate it - so perhaps
SystemImager can do that instead?
Perhaps the original author will have comment regarding it...
We did not start out using -S with rsync, but I think what triggered it
was some odd behaviour we were seeing with NetZero pulling images from
their mail servers -- si_getimage would never complete. I believe
that's when we started using -S.
It may be a bit of a speed hit, but I think we need to keep that option
in place. While the log file in question is a known, and we could
truncate it, that doesn't ensure that other files (in particular, user
created files) won't also be sparse. Therefore, I don't think that it
is appropriate to have per-file exceptions in this case.
I prefer to not have per-file exceptions in any case, actually. That
kind of solution will require additional attention in the future if
other similar files make their way into systems, or if filenames
change, etc. Whereas using the -S option will naturally handle future
changes of that type. I believe that using the -S option is a good
example of solving a problem, vs. treating a symptom.

oops... that's true! :-) it seems that rsync is able to hanle sparse
files, but it's very slow... tar, instead, seems to be faster.
Regarding lastlog maybe we could consider to exclude it (also
with utmp
and wtmp). IMO when you install a new image you don't want to preserve
the old logins informations of the golden-client...
