- We have a lot of reference source code ... which we'd like have appear
- read-only in our filesystem namespace. We also add new things regularly
- (and sometimes delete old things when the disks fill up).
-
- To manage our disk space, and to make life easier for sysadmins to add
- and delete files, we have most of our disks partitioned as one big file
- system per drive, this is mounted read-write. Source code is loaded onto
- this partition, and then sub-trees are loop-back mounted to their correct
- place in the filesystem (we use the convention:
- "/ref/{supplier}/{product}/{version}/..."
-
-
- Today somebody was browsing a source file via its "/ref" name using "vi" ...
- they were a little startled when they quit the editor to see it write the
- file back!
-
- Further investigation showed that the file system was correctly mounted
- read-only. Attempts to create new files failed, as did attempts to remove
- existing ones, likewise attempts to change the mode of files or directories.
-
- Anyone seen this? Is there a SUN patch to fix this?
