Close. That would be the source for the current state for 1.5.1_BETA,
not the exact source the snapshot was built against. That's probably
about the best you can do. For a current snapshot, you could use the
"-D" option, with the contents of the file "SOURCE_DATE" as an
argument. The problem with time-travelling on a branch, is that the -D
and -r options are stored in the same place, so they're mutually
exclusive, so including them both leads to "undefined behavior".

Yes. Often files are accidently checked into the tree with a "-kk"
flag, and then later fixed, but the "-kk" flag is sticky, so if you
check out a file in between, you'll fail to clear the flag (without
"-A"), through no fault of your own.  Also, if you mix "-D", and "-r"
tags, it seems to do want you want, at first, but then not so for
later "cvs update"'s. The only way to be sure what you're getting is
to use the "-A" flag.

For the same reason as above, I'd recommend always using "-A -rnetbsd-1-5".

Also, I find "-z?" only helps for a checkout, or when there's been a
major churn, with lots of files to download. For incremental updates,
it's faster without it. (Yes, I'm behind a modem.) Checking out the
whole tree over a modem is abominably slow, anyway -- it's probably
quicker to download a 1.5 tarball and convert it.
