booting the usb image

[Pierre-Philipp Braun]

Hi,

I tried to boot my laptop with both, dfly-i386-2.10.1_REL.img and 
DragonFly-i386-LATEST-IMG.img (20-Aug-2011) without any success.  When I 
press F1 (DF/FBSD) it just prints the message again.  The image should 
be fine and i've written it to the usb stick correctly, so I'm wondering 
what's going wrong?


Sorry I've got no additional symptoms nor informations to share in this 
situation.  It just doesn't work.  The bootloader seems to be happy with 
itself without letting F1 to go through.  Only F5 (Drive 1) works.


How is the memory stick image created?  I'm doing the NetBSD memory 
sticks myself and it works.  So my laptop's bios seems to be okay.


Thanks
Pierre-Philipp

Hi Olivier,

Thanks:-) But it's sloved enabling devfs for the guest, and the rules 
for that were missing in /etc/defaults/rc.conf and /etc/rc.d/jail. 
Maybe my reply didn't pass on the newsgroups though, since it hat patchs 
as joined documents.

Sounds like kernel version and ps binary don't match.
Are you sure they belong to the exact same DF version?

  nor ping,
  ping: socket: Operation not permitted

Raw sockets (thus ping) are disabled in jails by default,
for security reasons.  If you know what you're doing, you
can enable them with sysctl security.jail.allow_raw_sockets.

Best regards

 2.8.2).  Enabling procfs in the guest didn't help.  There's no device
 files appart from log, null and random but guests's dmesg says it's
 mounting devs.  I don't have any /etc/fstab but I don't think that's

Jail guest's dmesg was, of course, not his own, but real system's one. 
And devfs wasn't mounted.  Here are /etc/rc.d/jail and 
/etc/defaults/rc.conf patchs which fixes that (at least here) and allows,

jail_jailname_devfs_enable=yes
to be added into /etc/rc.conf.

The devfs issue was also experienced before 
(http://leaf.dragonflybsd.org/mailarchive/users/2009-10/msg00168.html)


Thanks:-)
