cvsup with tag=. on src and upgrading (in general)

[Richard Schilling]

I'm just getting into regular use with cvsup (way over do on that one), 
and I tried to specify a tag=. in the cvsup file.  Here's the file:


# This file specifies src files are to be uploaded.
*default host=cvsup2.FreeBSD.org
# *default tag=RELENG_5_1_0_RELEASE
*default tag=.
*default prefix=/usr
*default release=cvs delete use-rel-suffix compress
*default base=/usr/local/etc/cvsup
src-all




The documentation says tag=. will download the actual CVS directories 
so I can review changes/diffs, but I don't see them present in the 
code.  Just the top level directory has it and it looks like it's for 
4.X.

Did I do something wrong with the cvsup file?

Next question has to do with upgrading.  I have 4.6 src installed, but 
I cvsup'd RELENG_5_1_0_RELEASE.  Does jumping several 
releases/sub-releases like that cause problems?  Or, in other words, is 
it wiser to do incremental upgrades?
