[M3devel] Another CVS question: duplicate local copies

[Rodney M. Bates]

I understand a release tag is "sticky", meaning once I specify it in a
CVS command, the value I gave becomes internal state and will continue
to be used in subsequent commands, until I do something explicitly to
change it.  Where is this state recorded?  I particular, is it somewhere
in the repository, or on my local disk?

The motivation is this:  I am now connected through a satellite internet
service that has high latency, slow speed, and worst, a restrictive
quota on bit volumes.  I can scarcely afford the data transfer of
frequent switches between the head and release branches.  I want to
keep a local copy of each.  Can I do this?

I made a complete copy of my local distribution, currently of the
head.  In the copy, I did "cvs -z9 -q update -r release_branch_cm3_5_8".
So if I do an update in the future from inside the original directory,
will I get head versions, and if I do it in my copy that is now the
release branch, will I get updates to the release branch?  Or do I
have to specify tags carefully every time, no matter where I am?
Or is this feasible at all?
