| 14:54.50 | mgundes | As you know fork() is run commands with shell execution |
| 14:54.57 | mgundes | in default it uses "sh" as shell |
| 14:55.19 | mgundes | almost in every embedded devices busybox sh is used |
| 14:55.35 | mgundes | There is also bash standalone application can be used |
| 14:56.09 | mgundes | Is there any difference between standalone bash and busybox sh using with fork()? |
| 14:56.42 | mgundes | Does anybody have experience about that? |

| 18:33.31 | TheShagg | I am going to copy what I posted in #buildroot: |
| 18:33.56 | alex4nder | hey |
| 18:34.18 | TheShagg | I am trying to get a buildroot filesystem to an embedded-arm target using NFS, in an automated way |
| 18:34.34 | TheShagg | mounting the ext2 image from buildroot as a loop device doesn't seem to be visible over NFS |
| 18:35.12 | TheShagg | and I can't copy the files to the real host file system because there are devices in the /dev/ folder |
| 18:35.26 | TheShagg | so I can't figure out how to do automated test |
| 18:37.51 | av500 | make a cramfs? |
| 18:37.59 | av500 | and mount that? |
| 18:38.02 | av500 | over nfs |
| 18:42.39 | TheShagg | let me look into this |
| 18:42.40 | TheShagg | thanks |
| 18:44.21 | TheShagg | I've never tried a read only file system before.... do you know anything about that? |
| 18:44.49 | av500 | well, you would want var and tmp not in it :) |
| 18:45.13 | av500 | but why cant you mount the rootfs over nfs? |
| 18:49.40 | TheShagg | apparently there is some reason that you can't see loop devices in the tree from nfs |
| 18:50.01 | av500 | why do you need loop devices? |
| 18:50.24 | TheShagg | buildroot produces a file system as an ext2 image |
| 18:50.27 | av500 | why not mount the rootfs frok nfs? |
| 18:50.30 | av500 | why not mount the rootfs from nfs? |
| 18:51.02 | av500 | buildroot also produces a rootfs folder |
| 18:51.06 | TheShagg | right |
| 18:51.16 | TheShagg | the problem is that folder does not have all the devices in the /dev folder |
| 18:51.22 | TheShagg | because you have to be root to do that |
| 18:51.36 | av500 | and you dont have the password? :) |
| 18:51.38 | TheShagg | you also have to be root to decompress the output TAR or ext2 file |
| 18:51.47 | TheShagg | I want to automate this for our build server |
| 18:52.14 | TheShagg | 1) build kernel, rootfs, etc 2) load target test board with the outputs 3) run some tests on target board |
| 18:52.26 | TheShagg | trying to avoid being root |
| 18:52.28 | landley | TheShagg: network block device. |
| 18:52.47 | TheShagg | landley: thanks I'll check that out |
| 18:53.08 | av500 | or mdev for devices? |
| 18:54.51 | TheShagg | landley: How would you imagine I use network block device? As in, what would be done on the host, and what would be done on the embedded target? |
| 18:55.26 | av500 | pardon my ignorance, but dont unix thin clients boot from nfs for decades? |
| 18:55.44 | landley | theshagg: network block device is essentially a way of exporting a loopback image across a network. |
| 18:56.12 | landley | On the device side you run nbd-client to associate a network address with a /dev/BLAH device. |
| 18:56.36 | landley | On the host side, you run "nbd-server myfile.img ADDR" to serve the image. |
| 18:56.37 | TheShagg | so I see 2 problems, maybe you can help |
| 18:56.47 | landley | is juggling 3 things but happy to help. |
| 18:56.51 | landley | has not read full backscroll yet... |
| 18:57.01 | TheShagg | 1) How do I build the image without using "cp" to put the files into it |
| 18:57.14 | landley | gene2fs. |
| 18:57.18 | landley | digs up reference... |
| 18:57.33 | TheShagg | alright, and is there a way to use it as a bootable drive? |
| 18:57.49 | landley | http://landley.net/hg/aboriginal/file/tip/root-image.sh |
| 18:58.02 | landley | You want the SYSIMAGE_TYPE == ext2 part. |
| 18:58.09 | landley | is being called away by work again... |
| 18:59.48 | TheShagg | I see that, but I already have an ext2 image, i need to turn that into a network block device |
| 18:59.59 | TheShagg | thanks for the help, I will look into it |
| 19:00.24 | av500 | nbd-server ext2.img ADDR |
| 19:00.27 | av500 | I would guess |
| 19:00.34 | av500 | since you have the image already |
| 19:03.04 | TheShagg | i just gotta figure out how to make it bootable |
| 19:03.05 | TheShagg | hehe |
