[Savannah-hackers-public] git migration status

[Bob Proulx]

There has been some progress, regression, and progress again on the
git server side of things.  On Friday I switched git over to the new
server around noon.  Initial tests were good.  Then about 5pm I saw
the first problem reports.  Permission denied pushing commits.  Drat!
I switched git back to the old server while debugging the problem.

The problem was that I had tested before the database migration and
the database migration broke the nfs server groups.  That has been
fixed.  I am once again switching git onto the new server.

I might as well mention here that the database has been migrated from
the old internal to the new internal0 VM.  That movement went very
well and was a low stress move.  I think I will go so far as to say
that it was completely invisible to users.  If all continues I will
ask Ruben to shutdown the old VM on Monday.

The detail of the problem Friday was that the rpc.mountd daemon on vcs
was started before having changed the libnss-mysql.cfg file and
retained the configuration past after having changed the embedded IP
address and account credentials.  This meant that after having
shutdown the old mysqld that it could no longer get user account group
information resulting in loss of permission.  I should have either
restarted all of the long running daemons such as that or have
rebooted to ensure that all were restarted after the configuration
change.  This same problem would also affect download too and I will
do this there when the time comes for it.

This resulted in git users seeing permission denied errors when trying
to push commits.  Sorry.  Fixed now.  Moving forward again.
