Stuff Michael Meeks is doing

Up early, prodded mail; helped out Matt, Joey with packaging, discovered a chunk of the team were lurking on #opensuse-moblin on the internal IRC server instead of freenode - and confused as to why so few were there.
Prodded at bits for GUADEC; ineffectual kiwi fiddling, prodded at trying to reduce osc build times. The compliation of mutter-moblin (on a build server, from clean) takes:

stage duration (secs)

jail setup to end SuSEconfig 402

pkg unpack 1

configure 27

make 72

install 5

files / debuginfo 6

lint / checks 3

finishing / cleanup 18

So - it seems like the clear majority of the time - 2/3rds is spent creating a chroot jail, which is (at root [sic]) just a filesystem image. Untarring that (for me) takes 125 seconds - but presumably with some cunning 'unionfs' or 'fuse' magic that could be made 'instant'; roll on btrfs. Of course mutter-moblin is higher up the stack - with 300+ build dependencies, but presumably decreasing wins could be had for pieces lower down the stack too with pre-canned file-systems.
Tony & John around in the evening to talk; interesting.
