Most of my experience is with Linux so this is where my assumptions come from. First, I didn't know that scroll lock was the secret to being able to scroll back in these text mode terminals; second, I didn't know that the arrow keys were then the appropriate means for doing so; and third, I assumed you had to reboot after playing in single-user mode. > For the next time: You can use mdconfig to temporarily > allocate a RAM disk, then use script to record the whole > console session (including fsck output), afterwards run > "mount -a" and copy the log fron the RAM disk to a more > permanent place. Just in case. This may well be coming. I had roughly 48 good hours. Now, it's crashing again. I suppose I can't be surprised if the remaining memory card has now gone bad (the vendor is sending me replacements for both, despite my saying only one had gone bad). I realized I had a 32GB partition available for use as a swap partition. I had deviated from the default installation by allocating an EFI partition. It's manifestly clear that this is not needed. And it's more than large enough (actually about twice the needed size) for a complete memory dump (I'm presently running on 8GB, but the specification is for 16GB). I've gone in with gdisk and changed that partition's type, so hopefully the next time, I'll actually get a dump. Not that I've figured out what to do with one once I have it. Having changed that file sytem type, it wanted me to reboot. So I did, and while doing so, went into single user mode to do fsck -fy. The first pass was not clean; but all the messages were about stuff at the end. I don't remember it all, but there are something like four things here, including some sort of bit map. It seems to be about at least part of how the file system keeps track of allocated and unallocated blocks. I've already turned off background_fsck, but it seems to do a fast fsck anyway. Right now, at least, that seems undesirable. Is there a way to force it to be more thorough?
