invoking rcs from emacs on vfat

invoking rcs from emacs on vfat

[Patrick Drechsler]

Hi,

for simple ascii files I use RCS invoked from Emacs
(vc-next-action: `C-x v v'). This works fine on linux file
systems (i.e. ext2/3). When the file is located on a vfat
partition it doesn't work as expected. To reproduce the error:

On a linux system open emacs with:

patrick@trurl:~$ emacs -q --no-site-file &

then open a file (`C-x C-f') junk.txt enter something and save it
(`C-x C-w /myvatmount/junk.txt') on a _vfat partition_. After
saving the file I would like to execute vc-next-action (`C-x v
v'; this works with a linux file system as expected). No matter
if I answer the following question (whether to create a RCS
subdirectory) with "yes" or "no" I end with the following error:

,----
| RCS/junk.txt,v  <--  junk.txt
| initial revision: 1.1
| ci: RCS/junk.txt,v: Operation not permitted
| ci: saved in RCS/,junk.txt,
`----

The vfat partition is mounted with "umask=000". 

Appears to be a case sensitive problem since the directory
created is named "rcs" and not "RCS". Is there a workaround for
this?

If that indeed is the problem, try frobbing this variable:

,----[ C-h v vc-rcs-master-templates RET ]
| vc-rcs-master-templates's value is
| ("%sRCS/%s,v" "%s%s,v" "%sRCS/%s")
|
|
| Documentation:
| *Where to look for RCS master files.
| For a description of possible values, see `vc-check-master-templates'.
|
| You can customize this variable.
|
| Defined in `vc-rcs'.
`----

E.g.

(setq vc-rcs-master-templates
       (append vc-rcs-master-templates
               (mapcar 'downcase vc-rcs-master-templates)))

Thank you Kevin. It turned out that the error was somewhere else.

YFTR: I noticed that I had forgotten to set the correct UID in
/etc/fstab. So although I had write permission (umask=000) RCS
was apparently only looking at the user attribute.

JFTR, the 2nd (from Tucker Sylvestro):

   This workaround also fixes the "Cannot set file date" problem
   when trying to save a file under CVS versioning to a vfat
   filesystem in emacs.
