* Is /usr/src a source tree that you created with a `cvs checkout'?
This should be obvious from the CVS/ subdirectories of all the directories
in the /usr/src hierarchy. If you don't have these CVS/ subdirectories
you're probably trying to update with CVS a source tree that was created
by CVSup. This won't work.
* The cvs checkout command is run in the wrong path.
The checkout (or `co') command of CVS will create the directory you're
checking out as a subdirectory of the current path. So by running `cvs
checkout src' in /tmp you'll create /tmp/src ... by running `cvs checkout
src' in /usr/src you will get yourself `/usr/src/src' which is definitely
wrong.
The `cvs update' command, on the other hand, updates files starting with
the current directory (unless told otherwise), so you'd have to be
*INSIDE* /usr/src to update /usr/src. The difference is subtle but very
important.
* To fix the ``cannot write /home/ncvs/CVSROOT/val-tags'' message run cvs
with the -R option.
When running against a remote repository, cvs should be run with -R, IMHO.
This way, it will consider the repository read-only and avoid attempting
to write files within it.
Remote repositories might also require you to `cvs login' first (if you
haven't logged in at least once in the past).
Bearing all this in mind, the correct sequence of commands to run in your case
would be:
a. If /usr/src is a checkout and not a CVSup-created directory:
# cd /usr/src
# export CVSROOT='anoncvs@anoncvs.FreeBSD.org:/home/ncvs'
# cvs login:
password for anoncvs@anoncvs.FreeBSD.org:
# cvs -qR up -APd -I '!' -I CVS -rRELENG_4_10 2>&1 | \
tee /root/cvs-update.log
Note the -R option to `cvs'.
The extra -I options make sure that `cvs update' will ignore only the CVS
subdirs of the paths it traverses. Any stale object files or other
unrelated to FreeBSD files found in your source tree (i.e. your kernel
configs) should show up as lines starting with "?". Useful to know if
your source tree is clean.
When the update is done you can skim through /root/cvs-update.log for the
details you might have missed while it was running.
b. If /usr/src is not a checkout but a CVSup-created directory:
You'll have to backup your sources and do a real checkout. This is going
to take a long time, since CVS is not so fast as CVSup; it also puts a
great amount of load to the CVS server so you should be a bit patient when
checking our large trees, like the entire src/.
So you should first back up your existing /usr/src tree.
# cd /usr
# tar cvf - src | gzip -9c -> src.tar.gz
# rm -fr src
Then checkout:
# export CVSROOT='anoncvs@anoncvs.FreeBSD.org:/home/ncvs'
# cvs login:
password for anoncvs@anoncvs.FreeBSD.org:
# cvs -qR co -rRELENG_4_10 src 2>&1 | tee /root/cvs-checkout.log
and look in `/root/cvs-checkout.log' for possible errors or anything that
could be wrong.
