What exactly is a "maintenance copy"?
I'm sorry if the terminology is unconventional. I installed a small v10.3 for maintenance purposes; it was one of your suggestions.
HD. That installation seems to work properly, but I don't understand why the boot sequence is as it is:
The maintenance copy has but one partition in addition to SWAP. In setting up the installation, I was very careful to arrange that GRUB be installed in the root partition, rather than the MBR. After setting the configuration and before confirming actual installation, I verified that this was the case. I expected therefore that the boot sequence would be: OS/2 Boot Manager, followed by whatever line of BM is chosen. What actually happens is as follows:
1) openSuSE (maintenance partition) Welcome screen, with its list of choices 2) I choose "Boot from Hard Disk"
That choice usually only occurs when booting from installation or recovery media. Did you ever remove the DVD from the drive after installing 10.3? Do you see a syslinux message briefly on screen before the Welcome screen?
Ach!! I never removed the DVD from the drive -- even after the installation was complete. It's so obvious. Well, I've taken it out now, and am deeply embarrassed. I can only apologize for bothering you and Rajko unnecessarily. Of course now the boot sequence is exactly what it should be. Tomorrow or the next day I'll do the necessarily retrieval of data that was not backed up. Then I'll install v10.3 over the failed upgrade, but with some changes in partitioning. I will alloacate 20GB for /root and the same amount for /home, so that user apps and data will not be affected by any future upgrading disaster. All the partitions are EXT3 (no more XFS). Therefore no need for special partitions in which to put GRUB -- I eventually learn lessons; it just takes more time than it used to. If it is true that OS/2 supports a EXT3 driver, I might instead do away with the maintenance partition, and rely on OS/2 (actually eCS v1.1) for emergency manipulation; I have to think about that.
The easiest solution for you might be to boot into OS/2 and reinstall standard MBR code with DFSee or LVM.EXE, and at the same time verify that the 0Ah partition is marked as the only active/startable partition in the master partition table.
It is, of course. Many, many thanks .... and apologies. -- Stan Goodman Qiryat Tiv'on Israel "Windows - a hairball of software" -- Scott McNealy, Sun Microsystems -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

MANY thanks for this. I had no feel whatever (as you saw) for the future needs of partition sizes, and my numbers were just a guess -- but not a bad one, apparently, judging from yours. I could enlarge /home as you have done.

Did you try df yourself? It isn't a disk partition. It's a virtual filesystem. Man udev. -- Jesus Christ, the reason for the season. Team OS/2 ** Reg.

Be aware that size of /home depends on what for computer is used. I don't have much of multimedia files, but I do have virtual drives (for virtual machines in VirtualBox and QEMU) that take few GB each (currently 8) so my /home is still too small, and right now I'm using extra 40 GB partition that was initially meant to be archive. So satisfying total for my use case would be some 60 to 70 GB.

It is not separate. It is just udev subsystem entry in /etc/mtab. You can run: cat /etc/mtab to see that and few more. Here is output of mine /etc/mtab: /dev/sda6 / reiserfs rw,acl,user_xattr 0 0 proc /proc proc rw 0 0 sysfs /sys sysfs rw 0 0 debugfs /sys/kernel/debug debugfs rw 0 0 udev /dev tmpfs rw 0 0 devpts /dev/pts devpts rw,mode=0620,gid=5 0 0 /dev/sda7 /home ext3 rw 0 0 securityfs /sys/kernel/security securityfs rw 0 0 I have no idea why command 'df' picked udev. Maybe it uses some portion of /dev directory, so it really exists on hard disk, while other mounts without slash in front of them, like proc, sysfs, debugfs, securityfs exist only in RAM.

I think for my present use, the 20 - 30GB is more than adequate. But that wasn't what was troubling me; I had no feel at all for what might be a reasonable size for the OS itself, i.e. for the / partition. I now feel more confident. I will need to investigate the use of virtual drives, but I think making use of them is probably something for the future, if at all.

The upshot of having taken the trouble to try to retrieve the contents of the /home directory of my failed upgrade is the revelation that I need not have bothered. After I mounted the /dev/sda6/home (sda6 is the entire old system), dir showed a content of zero. I am very surprised that an update, no matter how screwed up it becomes (and especially without giving any hint of trouble during the "upgrade process", can actually delete the entire content of the installation. Yet openSuSE seems to be up to that task. So thanks again for all those who helped me along to get to this point. First thing tomorrow mornind, I will install v10.3 anew, without the need to bring over anything at all from the destroyed v10.2. -- Stan Goodman Qiryat Tiv'on Israel Old Fart n. slang (old fart'; in New England, old faaht') Tribal Elder.
