Announcing the public release of Supermount-0.4a.
Supermount is a kernel patch which transparently supports removable
media. You can mount the supermount filesystem on a mount point such as
/floppy or /cd even without a disk in the appropriate drive, and
supermount will automatically take care of mounting and unmounting the
sub-filesystem, msdos or iso9660, as disks are inserted and removed.
With supermount, you can simply place a msdos-formatted disk in the
floppy drive, copy a few files to it, and remove it. Supermount
guarantees that write-operations like copying or renaming files do not
return to the user until all writes have been flushed to the disk. When
you get the command line prompt back, you can be sure it is safe to
remove the disk.
You can even safely remove the disk if you have a process cd'ed into a
subdirectory of the mounted media. For example, if you do a "cd
/floppy/subdir" and remove the disk, you'll simply get an IO error on
doing subsequent "ls"es until you insert a new disk, at which point "ls"
will show the root of the new disk.
Supermount has been tested on cdrom and on floppies, using the dos and
iso9660 filesystems. Other linux filesystem types should work too, but
only in read-only mode (this will be addressed in later versions). I've
had a number of people testing supermount fairly extensively for over a
month now, including a public-access internet site where we needed it to
allow users to easily download files to floppy on a Linux system.
There have been no bugs reported in the last couple of versions of
supermount (the only changes have been performance improvements and a
port to 1.3 kernels) so I'm now making a public release.
The tar file for supermount includes a README plus kernel patches for
1.2.13 and for 1.3.30 (which should also work on kernels up to 1.3.34).
Note --- the cdrom support has so far only been tested on ATAPI EIDE
cdrom drives. Please let me know if you encounter problems on other
hardware.
Enjoy!
