| 17:00.35 | Pali | or also comes from upstream? |
| 17:00.45 | freemangordon | Pali: libc is maemo eglibc |
| 17:01.31 | Pali | so we take current debian armhf port with thumb2 enabled binaries and it can run on n900 without any problems like hw errata segfaults? |
| 17:02.03 | freemangordon | yes |
| 17:02.31 | Pali | ok, that is great |
| 17:02.38 | freemangordon | I ran devuan lxde a week or ao ago without any problems |
| 17:02.56 | freemangordon | build with devuan arm-sdk |
| 17:03.10 | freemangordon | which I guess uses upstream gcc |
| 17:03.46 | freemangordon | Pali: by the way, do you have any idea how to test iphbd? |
| 17:04.17 | Pali | start dsme and use it |
| 17:04.25 | Pali | dsme is heavy user of iphbd |
| 17:04.25 | freemangordon | I mean - I have it REed, but what this is supposed to do? |
| 17:04.28 | freemangordon | hmm |
| 17:04.58 | freemangordon | I am trying to do that in devuan 64 bit chroot :) |
| 17:05.07 | freemangordon | lemme see if dsme will start there |
| 17:06.00 | Pali | http://talk.maemo.org/showthread.php?t=89709 |
| 17:06.50 | freemangordon | Pali: hmm, how to start dsme? |
| 17:07.04 | Pali | it is started by upstart |
| 17:07.15 | Pali | try to look at /etc/event.d/dsme |
| 17:07.42 | freemangordon | yes, but this is chroot, is it safe to install upstart there? and eve installed, who is going to start it? |
| 17:08.50 | freemangordon | hmm: |
| 17:08.53 | freemangordon | dpkg: considering removing sysvinit in favour of upstart ... |
| 17:08.54 | freemangordon | dpkg: yes, will remove sysvinit in favour of upstart |
| 17:08.54 | freemangordon | dpkg: regarding upstart_0.3.8-68+0cssu9_amd64.deb containing upstart: |

| 17:09.21 | freemangordon | Pali: ^^^ |
| 17:09.49 | Pali | maemo's upstart is different as debian's |
| 17:10.06 | Pali | it will not work |
| 17:10.26 | Pali | look at dsme's script /etc/event.d/dsme how to init daemon starting it |
| 17:10.31 | Pali | and start it manually |
| 17:10.33 | freemangordon | ok, is it ok if I remove csysvinit-core and install maemo upstart? |
| 17:11.01 | Pali | if you do that on debian/ubuntu you will get unbootable system |
| 17:11.03 | freemangordon | mind you, this is chroot, so even if I screw it, it is not a problem |
| 17:11.13 | Pali | upstart is init daemon |
| 17:11.14 | parazyd | freemangordon: arm-sdk uses my toolchains to compile the kernel, all other bins/libs are made with vanilla (as in debian) |
| 17:11.27 | Pali | same as systemd or sysvinit |
| 17:11.35 | freemangordon | parazyd: thanks |
| 17:11.36 | Pali | in chroot you are not running any init daemon |
| 17:11.47 | freemangordon | yes, but I guess I can start it by hand |
| 17:12.08 | Pali | yes, look at that script how upstart starting it |
| 17:12.13 | Pali | and start it manually |
| 17:12.22 | freemangordon | Pali: so, it is safe to replace sysvinit with upstart, correct? in chroot that is |
| 17:12.23 | parazyd | is upstart the only init that suffices? |
| 17:12.36 | Pali | why you want to replace it? |
| 17:12.49 | Pali | or what do you want to achieve? |
| 17:12.52 | freemangordon | because dsme in even.t is not that simple |
| 17:13.05 | Pali | in chroot you are not running init daemon |
| 17:13.09 | Pali | so it will not work |
| 17:13.19 | freemangordon | Pali: yes, but I can start it by hand I guess |
| 17:13.30 | freemangordon | or not? |
| 17:13.34 | Pali | what do you mean by hand? |
| 17:13.44 | Pali | by hand = look at script and type commands manually |
| 17:13.48 | parazyd | you should rather run it all in a qemu |
| 17:13.48 | freemangordon | like /sbin/upstart or whatever the binary is |
| 17:13.55 | Pali | that will not work |
| 17:14.09 | Pali | as I wrote in chroot you are not running init daemon |
| 17:14.16 | Pali | init daemon = process with pid 1 |
| 17:14.18 | freemangordon | Pali: ok |
| 17:14.30 | sicelo | install systemd :) |
| 17:14.34 | freemangordon | parazyd: for initial stages chroot is easier to setup |
| 17:14.54 | Pali | sicelo: freemangordon is in chroot, it will not work too |
| 17:15.01 | freemangordon | :D |
| 17:15.06 | parazyd | :D |
| 17:15.08 | sicelo | :P |
| 17:15.08 | freemangordon | Pali: don;t bet on that |
| 17:15.41 | freemangordon | after all, this is systemd, I would not be suprised if it does kexec on it's own kernel to take over the machine from chroot :D |
| 17:16.45 | freemangordon | Pali: what are the chances for dsme to reboot/shutdown my machine once started? |
| 17:17.21 | Pali | it is possible |
| 17:17.53 | Pali | not dsme itself, but some module |
| 17:17.59 | freemangordon | :) |
| 17:18.16 | freemangordon | anyway, it refuses to start because it cannot read R&D flags |
| 17:20.12 | KotCzarny | hmm, idea |
| 17:20.24 | KotCzarny | separate init daemon from maemo core daemons |
