DragonFly, NFS, and netbooting

DragonFly has historically performed very well with NFS.  I don’t have hard numbers to point at (an interesting exercise if someone wanted it), but in any case: DragonFly now can tune up to a much larger iosize, which means better NFS performance.  DragonFly <-> DragonFly NFS performance can now max out a GigE link, or with anything else that can handle the larger iosize.  That plus additional readahead, also in that commit, means easier netboots.

Binary dports for DragonFly 4.5 users

Since DragonFly 4.4 has been branched, bleeding-edge DragonFly is now at version 4.5.  As John Marino detailed in his post, that means pkg on 4.5 systems will look in a new place for downloads.  (“dragonfly:4.6:x86:64”, since it always uses even numbers)   To cover for this, set ABI to point at DragonFly 4.4 packages in pkg.conf for now.  They’re freshly built and functionally the same, anyway.  Once there’s a 4.6 download path, that ABI setting can be removed.  Packages for DragonFly-current are available now and probably at the mirrors by the time this posts.

Update: as John Marino pointed out to me, anyone on DragonFly-master who upgrades now will be at version 4.5.  This means pkg will get the new (4.5) packages on the next pkg upgrade.  That means a mix of old and new packages unless you either reinstall anything (pkg update -f) or hardcode the 4.4 download path until you are ready to switch everything.

So: DragonFly-current users should either hardcode the 4.4 path for now or force an pkg upgrade for everything.  DragonFly 4.2-release users are unaffected.

 

True and False code reading, NYCBUG edition

NYCBUG is having “true(1) and false(1), The Classical Code Reading Group of Stockholm, NYC*BUG Mix Tape Edition” happen this Wednesday the 7th.  You may remember a similar event at the end of August.  This will be led by George Brocklehurst from the original event, with NYCBUG members present.  If you missed the previous one, try this out – by all accounts, these code readings are inordinately fun.

DragonFly 4.0 users should upgrade

If you happen to still be running DragonFly 4.0 – that’s two releases ago and not supported – you may be noticing less ports are building.  There’s been enough significant changes in DragonFly since that release that it’s reducing the number of buildable ports.

DragonFly 4.0 to 4.2 is not a difficult jump, so jump when you can.  The converse of this, of course, is that there’s even more building on 4.2 and DragonFly-current.
