New release 0.0.50 at
ftp.nvg.ntnu.no:/pub/vms/freevms (freevms-0_0_50.tgz and linker-0_0_45)
(Linker might not change each time)

Cluster changes (had to follow up on the I/O-structure changes from last time).
Lock manager, DCL logicals.

In general:
New config file /vms\$common/sysexe/params.dat must have SCSNODE=name.
This replaces/will replace the use of hostname for clustering.

An ODS2 fileimage must be mounted before clustering is started if
it is to be read by the other node.
Afterwards, the other node must mount it with name$dfa0 etc.

DCL got support for creating name tables, defining and showing logicals.
(But logicals are currently used nowhere else)

Functional lock manager (non-distributed), with two example programs
enq and enq2. The two programs are also tested on VMS, and I
got similar behaviour (output on i386 is bad, and ASTs in userspace
on uml does not work). I have run two instances of each at the same time.

New bug:
Clustered stop got some problems.

On i386, do not use a gcc as recent as 3.3.

Short-term I/O and other plans:
(Same as before, wanted this time to give priority to clustering and locks)
Let RMS also use Ext2 with write support.
Execute programs with execve and imgact on Ods-2.
Get more/better write-support in.
Do more SCA/SCS stuff.
At least look at whatever "device" uml uses and NE2000.
After some time even more driver support might be cut/broke (the most).
