[02:17] <MrCurious> anyone know why ubuntu on pandaboard dedicates 320meg of ram to a tmpfs for dev, dev/shm, var/run, and var/lock?
[04:02] <MrCurious> better question does anyone know how to change it so that tmpfs is not used? i have the fs moved to a fast usb disk
[04:24] <MrCurious> ugh, unrolled uInitrd, but cant work out exactly how it is sucking up > 300M for a tmpf
[04:27] <MrCurious> can anyone spare a hint on how to disable this tmpfs on 11.04 omap4
[04:28] <MrCurious> anyone here awake?
[14:25] <uragano2> Hello!i don't know where set JAVA_HOME...where is it?
[21:49] <persia> MrCurious, By default, all tmpfs mounts are allocated 1/2 available RAM.  In practice, very little of this should be used (perhaps 1M for all of /dev, /dev/shm, /var/run, and /var/lock combined).  If you have more usage than this, you're probably running something that uses SHM (shared memory regions) heavily: attempting to put that on rotary media (or anything other than RAM) is likely to have a significant negative effect on performance.  If yo
[21:49] <persia> u are encountering OOM issues, consider adding swap on your rotary disk.
[21:49] <MrCurious> persia: thanks, i sorted it out
[21:49] <MrCurious> it was due to being a upgraded 10.10
[21:50] <MrCurious> it was set to only use 3/4 of the mem
[21:50] <MrCurious> modified a boot flag
[21:50] <MrCurious> and re-enabled a missing segment of 256meg
[21:50] <persia> Ah.  The 320 looked like some memory was missing, and now it all makes sense :)
[21:51] <MrCurious> yup
[21:51] <MrCurious> now its on to building the software stack that i need
[21:52] <persia> Excellent.
[21:57] <MrCurious> dont suppose you know the name of the package that contains linux/videodev.h
[21:57] <MrCurious> guessing a kernel header package or kernel package
[21:58] <MrCurious> linux-source :D
[21:58] <MrCurious> its coming back to me now
[22:06] <persia> linux-headers-${FLAVOUR} is probably lighter-weight and more likely to match your needs.  In this case, `linux-headers-omap4`
[22:08] <MrCurious> tried
[22:08] <MrCurious> it lacked the file
[22:09] <MrCurious> 75% done unpacking the full kernel
