Subject: [ANNOUNCE] System V filesystem
Sysvfs is an implementation of the System V and Coherent and Xenix
filesystems for Linux. It grew out of separate filesystem implementations
Xenix FS Doug Evans <dje@cygnus.com> June 1992
SystemV FS Paul B. Monday <pmonday@eecs.wsu.edu> March-June 1993
Coherent FS B. Haible <haible@ma2s2.mathematik.uni-karlsruhe.de> June 1993
and was merged together in July 1993.
This is version alpha 5.
To install:
* You need Linux 0.99.10 or newer.
* Go to /usr/src/linux, unpack the tar file there, and patch the Linux source:
patch -p1 < sysvfs.cdif
To build the Linux kernel with the patches:
make config
make depend
make
* To mount a disk or a partition, use
mount [-r] -t sysv device mountpoint
The file system type names
-t sysv
-t xenix
-t coherent
may be used interchangeably, but the last two will eventually disappear.
Bugs in the present implementation:
- Coherent FS:
- The "free list interleave" n:m is currently ignored.
- Only file systems with no filesystem name and no pack name are recognized.
(See Coherent "man mkfs" for a description of these features.)
- SystemV Release 2 FS:
The superblock is only searched in the blocks 9, 15, 18, which corresponds
to the beginning of track 1 on floppy disks. No support for this FS on hard
disk yet.
