Vikas is, of course, wrong ~:^) Just trying to check if you're out
there, Vikas.  Something everyone needs to try to keep in mind is that
this issue is about Linux, and is not relevant to OpenBSD.  This is not
an upgrade issue since there is no previous Linux release to upgrade
from, and upgrade is purposely not designed to upgrade from submittal to
submittal.  Since the Linux side of things are still a WIP, things may
change that have to be addressed by doing a flash install, or perhaps
some manual steps, that won't ever be handled by upgrade.

To reiterate:

Because the Linux part of our distribution is a WIP at the moment, it
is best to do "flash_install upgrades" rather than the traditional
system upgrade.  This is because changes from a previous submittal
often require changes to config file formats or other things that
cannot be addressed by system upgrade.  A "flash_install upgrade" is
where you create a flash with the flash_install.sh command, and then
tell it to copy the config files from the primary flash, and then boot
the new flash.  Sometimes even this isn't sufficient and a manual
process may also be involved.  Hopefully in those cases someone will
remember to send out a specific email detailing that process.  And by
someone, I mean me, because most other folks seem to remember handily.

Cheers,

a
