Hi,
I had tried out the /dev/anon patch on a host server, success wasn't too
good. It crashed after a few hours of running. This was without
ubd=mmap passed to the UML's. Unfortunately I do not have any sort of
OOPs.
Now the interesting part, I rebooted with the previous kernel so it does
not have the /dev/anon kernel patch. The /dev/anon device still exists
and the UML's are using it!
My primary question now is, is this a "bad thing" to do? Would there be
any significant performance problems to just let it run this way?
Shouldn't the UML kernel check to make sure that /dev/anon kernel
support is indeed there?
Thanks,
Matt

This may just be noise, but I also had a host server with 2.4.24 + skas3 + /dev/anon that crashed yesterday after a day or so of running. Not using ubd=mmap.

Yeah, the patch is not quite kosher. I've had no problems whatsoever running
skas UMLs, but tt UMLs won't boot with devanon.

I don't go near tt UMLs. This these are all using skas UMLs. Is there anyway I can disable /dev/anon without rebuilding the kernel. rm /dev/anon?

Yes, that will work. I forgot to mknod /dev/anon the first time I
tested it and the UML's did not use it.
I'm still perplexed as to my situation though :)

That'll work. I chmod 600 /dev/anon, but it works out the same.
