Re: Issues with network file systems and CVS

[Adam Bregenzer]

AFIAK the issue is not with where the working copy is stored, as long as
you are the only one accessing the working copy.  The issue is where the
repository is stored/accessed from.  Replacing the CVS protocol that's
using pserver in your diagram with a local protocol accessing the
repository via smb is bad, ie:
-------------------              --------------
|Linux CVS        |              |Windows     |
|Server           |              |Workstation |
| --------------- |              |            |
| |       | C P | |              | ---------- |
| | Repo  | V S | |              | | WinCVS | |
| |       | S E | |     protocol-->| Client | |
| |       |   R | |     |        | ----^----- |
| |       |   V | |     C        |     |      |
| |       |   E | |     V        | ----v----- |
| |       |   R | |     S        | | Mapped | |
| --------------- |     -:local:-->| Drive  | |
| |       | S S | |              | ----^----- |
| | Work  | M H | |              |     |      |
| | Dir   | B A |<--SMB protocol--------      |
| |       |   R | |              |            |
| |       |   E | |              --------------
| --------------- |
-------------------

in other words your CVSROOT shouldn't be:
:local:M:\cvs
if M is a mounted share.
it needs to use pserver, gserver, ssh, rsh, or some other remote
protocol.
