Changing root password from stdin value
Hello, I'm trying to get some scripts working which would take a password from stdin and set it for root. In Linux "passwd --stdin" is used, in FreeBSD "pw mod user root -h 0". How would I do this in OpenBSD? Thanks, Lucian -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro

openbsd "sysprep"?
Hi, I'm trying to build a Cloudstack OpenBSD template and I need to do a bit of cleaning up on it before I let people use it. Besides changing the password, wiping the shell history, ssh keys, random seed and /var/log stuff, what else should I be doing to trigger a more "unique" installation?

Live resize / filesystem?
Hello, Anyone knows is it's possible to live resize a partition and it's filesystem? I'm working on some OpenBSD cloud templates and I need them to be - among others - "self-resizable". I.e. the main template will be 8 or 10 GB whereas the destination disk may be larger than that; the OS should expand it's partition to match the entire disk.

Re: Live resize / filesystem?
Thanks guys, I was hoping for a more optimistic feedback, at least I know not to waste too much time on this. Lucian -- Sent from the Delta quadrant using Borg technology!

shutdown/reboot on acpi/qemu signals
Hello, I'm having an issue with my OpenBSD cloud instance in that it completely ignores the signals sent to it by qemu-kvm, so instead of getting shut down or rebooted gracefully it has to be "reset". Anyone hit this issue before and can advise on the matter? Thanks, Lucian -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro
Re: Live resize / filesystem?
Otto, Thanks, but this will be a "cloud template", all other templates I'm building (linux, freebsd) expand partition and filesystem upon first boot, was hoping to achieve the same. Not sure how reinstall would help in this case, though I am open to any advice. Lucian -- Sent from the Delta quadrant using Borg technology!

Re: shutdown/reboot on acpi/qemu signals
Giancarlo, Thanks, but for me it did not work, the guest fails to boot after this change. I'll wait for 5.6 for more serious work on KVM. Thanks!

Re: Live resize / filesystem?
Alexander, Nice idea, better than getting stuck with same size. I know this is very relative, but which partition gets used most in OpenBSD in your experience? /var or /home?
