Subject: bring out your dead - eschatology questions
1) eupdate(1M) works in single user mode only, otherwise it chokes to death
------- on eu's lockfile
2) escher(1M) dies with the words:
------
'pnames: ioctl error on Eschatoloy 1, errno 16, raw device /dev/rdsk/c0d0s0'
These couldn't possibly be bugs, [Apple: "the power to be your best"... S:-|]
so, does anybody know what I'm doing wrong?
3) How can I actually LOOK at the 2 Eschatology file systems? Mounting
the device nodes which remain after eupdate dies, doesn't work. I'd
like to know how much space is left there, in order to decide which files
to add to the eschatology list.
4) I remember how one of my MacApp-lications in development died, because I
forgot to supply the function return value (an object), and apparently
Object Pascal tried to call one member function of the random pointer,
and, jumping into an interesting area of code, ended up overwriting
- at least - the driver partition of the disk.
With A/UX, it's no problem dd-ing the first 128 blocks of the physical
disk (/dev/rdsk/c<n>d<m>s31) to a floppy, thus conserving Block 0,
partition map, and Apple_Driver. So I assembled a floppy with tiny system
folder, sash, minimal standalone A/UX utilities - and found out, that I
didn't have a chance to eject the A/UX-boot floppy from ;sash', and so
couldn't access the vital data I had saved on the above mentioned floppy.
Any ideas?
Necrophobiously,
