| 16:42.42 | jxqz | jlp_znc: no, no, indeed |
| 16:43.56 | jxqz | shalkie: I thought of apparmor too, but does it have its devious hooks into ordinary utilities such as /bin/bash even if the service itself is not running? |
| 16:44.49 | jxqz | I was able to sucessfully chroot to /new/root by copying in a statically compiled /bin/bash, but nothing else besides /bin/bash works |

| 17:18.56 | youtah | Oh yeah, well, your mom is older than you... |
| 17:21.39 | jxqz | jlp_znc: that's the confusing part because /new_root is supposed to be a vanilla ubuntu 12.04.4 system |
| 17:23.25 | jlp_znc | jxqz: can you run ldd in the chroot? we used to run chrooted redhat systems on our ubuntu dev hosts at raytheon all the time, so I know technically it is feasible. |
| 17:25.21 | jxqz | for chroot to work, I thin you only need architecture compatability |
| 17:27.19 | jxqz | ldd /bin/ls |

| 18:40.27 | Oberon4278 | Endianness is a property of an individual processor, not an OS, right? |
| 18:40.52 | goozbach | Oberon4278: as I understand it yes |
| 18:40.58 | Oberon4278 | ok |
| 18:59.23 | jsmith | Oberon4278: Well... a little-endian OS isn't gonna run very well on a big-endian processor |
| 18:59.39 | jsmith | Oberon4278: So yes, the endian-ness of the OS has to match the processor |
| 18:59.40 | Oberon4278 | right |
| 18:59.46 | Oberon4278 | but it's the processor that dictates it |
| 18:59.52 | Oberon4278 | is what I'm wondering |
| 18:59.52 | jsmith | Sure |
| 18:59.55 | Oberon4278 | ok |
| 19:05.29 | tomstokes | Some CPUs are bi-endian. You can choose the endianness |
| 19:05.45 | tomstokes | But it's one or the other at boot time. You can't change on the fly. |
| 19:06.05 | tomstokes | Mostly just a MIPS thing, which is probably going to be relegated to history soon |
| 19:07.39 | Oberon4278 | MIPS? |
| 19:09.28 | Oberon4278 | Ah, I see. |

| 20:05.58 | jlp_znc | also, it's really annoying when people say something like "can I ask a question?" and then they leave. :-) |
| 20:06.22 | jlp_znc | and what's wrong with mips? mips was a great architecture. |
| 20:06.31 | jxqz | exactly |
| 20:07.32 | jlp_znc | still has his mips book kicking around somewhere |
| 20:08.01 | jlp_znc | description of the R2000 architecture (I think it was the R2000) |
| 20:10.02 | ezakimak | isn't R2000 the ancient one? or am I confusing it with chip generations? |
| 20:10.19 | ezakimak | the last mips box I sold had an r10k chip |
| 20:10.35 | ezakimak | and r12k was out |
| 20:10.49 | jlp_znc | R2000 was the ancient one |
| 20:11.21 | jlp_znc | it was the first one I saw used in systems. I remember we had some machines with R6000 chips in them, too. |
| 20:11.47 | ezakimak | wasn't dlx essentially mips? |
| 20:11.50 | jlp_znc | had an 8-way machine before multiprocessing was cool. :-) powell.math.byu.edu |
| 20:12.07 | ezakimak | my mips boxes were all surplus from byu |
| 20:12.14 | jlp_znc | and I think hamblin.math.byu.edu was an R3000 |
| 20:13.01 | ezakimak | a bunch of indys, some indigo2s and their very first: "tank" and it's sibling |
| 20:13.15 | ezakimak | sorry not indigos, O2s |
| 20:13.42 | ezakimak | i remember logging into "tank" my freshman year when it was in service |
| 20:13.45 | jlp_znc | powell was like a headless O2, I think |
| 20:13.59 | ezakimak | i had 3 O2s |
| 20:14.03 | jlp_znc | tank was the fileserver, as I recall. |
| 20:14.15 | ezakimak | sounds about right |
| 20:14.19 | jlp_znc | I set all that stuff back in the early 90s. |

| 20:15.09 | jlp_znc | I had an indy on my desk. don't remember it's name, though. |
