Dear Release Manager,
as we discussed on IRC today (and which I had not realized until
today) the 8.2.1 release will be pre-installed on XOs for much longer
than anticipated, since the 9.1 release has been canceled, and no
replacement is in sight.
We have had fixed Etoys / Squeak-VM package
We didn't schedule one, but in case anyone thought there would be, there is
no ActivityTeam meeting this Friday.
I'm out of town this week, and I'm leaning towards bi-weekly anyway. I'll
send out another email when we set the next time.
Cheers,
Wade

I am the author of the page in question. To establish my credentials, I
wrote my first filesystem forensic tool in 1980, to diagnose and repair
a Unix filesystem that had been damaged by a kernel misconfigured that
made it swap on top of the filesystem. That was when 10 MB disk packs

To me, one of the most attractive points about the OLPC is the
capability to use it collaboratively "far from civilization".

Hi,
I have modified the XO activation initramfs to attempt to locate a
lease server on an XS on each open infrastructure network that can be
found (early patch attached).
The XS does not bind the server to the IPv6 address correctly (perhaps
we can work on that)., so it currently runs over IPv4
