15:57.10yebyenanyone around?
15:58.50Wizardme
15:59.15yebyenhowdy :D
15:59.27Wizardhi yebyen
15:59.31yebyendon't suppose you know a lot about reiser4 root partition?
15:59.55yebyenother than it works great in elive
16:00.06yebyeni'm trying to get a new squeeze installation to use it
16:00.23Wizardhmm, grub2 supports it, methinks
16:00.41Wizardyou can allways create good, old ext2 /boot :>
16:00.44yebyeni have read you can do it with a patch
16:00.48yebyenbut i'm not interested in that
16:00.49yebyenyeah
16:00.53yebyeni made reiserfs /boot actuallly
16:00.57yebyenand it loads the kernel and initrd ok
16:01.06yebyenbut initramfs can't mount /dev/sda2 on /root: no such device
16:01.19Wizard<PROTECTED>
16:01.26yebyenthat's how initramfs does it
16:01.30Wizardwhy do you need /root on separate partition?
16:01.39yebyenit mounts on /root and then chroots in later when it's ready
16:01.50Wizardah, that way
16:01.58yebyenbut if it can't mount
16:02.09yebyenit can't find anything like /sbin/init or that really important stuff
16:02.21yebyenand it has no trouble mounting other sane filesystems
16:02.28Wizardyeah, did you create initrd by yourself?
16:02.38yebyenthe reiser4.ko and zlib_deflate.ko modules are present
16:02.48yebyeni manually jiggered update-initramfs a few times
16:03.00yebyeni'm using liquorix kernels from the zen-kernel series
16:03.12Wizardbuilt vy yourself?
16:03.12yebyenit has reiser4 support
16:03.25yebyennah, liquorix is a debian sid/squeeze kernel vendor
16:03.32yebyenthe kernel works great with squeeze, it's marked as for sid
16:03.40Wizardmhm
16:03.49yebyenso i can boot the kernel into a non-reiser4 rootfs
16:03.55yebyenand mount the reiser4 ok
16:04.03yebyenbut when it tries to go from initramfs, no go
16:04.23yebyeni read one thread that says something is trying to use fsck to detect the partition types, and thats why it fails
16:04.35Wizardseem that initrd is borked
16:04.38yebyenbut i do have fsck.reiser4 on the host partition, and fsck doesn't seem to be in the initramfs
16:04.41Wizardlook into it's /dev dir
16:04.52keyrayebyen: to use more than 4 GB of ram in elive, go to the nurse mode and install the special kernel
16:04.56yebyen/dev/sda* and /dev/disk/* are all where they expect to be
16:05.10yebyeneven /dev/disk/by-label/Squ-20110222
16:05.12Wizardthan why it says no such device?
16:05.19yebyenbecause it doesn't like the filesystem
16:05.26yebyenreiserfs /dev/sda1 mounts fine from initramfs
16:05.33yebyenmodprobe reiser4, modprobe zlib_deflate
16:05.36yebyendon't help any
16:06.04yebyenmore specifically why does it say no such device, i would like to know
16:06.08yebyentoo
16:06.19yebyenmount -v is no help
16:06.29Wizardhmm, and /dev is proper, right?
16:06.35Wizardhow did you check this?
16:06.44yebyenls /dev/sda*
16:06.55yebyenmount -t reiserfs /dev/sda1 /root
16:06.59yebyena-ok
16:07.19yebyeni need the compressed reiser4 for my root since this is one of those 2G eeepc devices
16:07.49Wizardah, yebyen, ls in initramfs mode?
16:08.01yebyenyes
16:08.06Wizardso you actually booted that and gave it there?
16:08.19yebyenthe first thing it does is says, failed to mount
16:08.29yebyenthen it ceremoniously fails to mount /root/dev /root/proc /root/sys
16:08.37Wizardo_O
16:08.41yebyenthen it dumps me at (initram) prompt
16:08.45Wizarddamn strange
16:08.52Wizardand all /dev/* are on place?
16:08.56yebyenyeah
16:09.01yebyenin the /dev
16:09.03WizardO_o
16:09.08yebyennot in /root/dev for target system
16:10.02yebyeni can even launch x11 from in the chroot
16:10.10Wizardand mounting it by hand does not work?
16:10.13yebyenbut i am booting from this unreliable /dev/sdb1 4G sdcard
16:10.15yebyenfive year old
16:10.36yebyenyou can mount it by hand using the kernel, if you boot with something that initramfs doesn't fail on
16:10.41yebyenlike my ext3 /dev/sdb1
16:10.52yebyenjust a small squeeze system with nothing you don't need outside of the first 500MB
16:11.02yebyensince later parts of that card are corrupt
16:11.27yebyenyou can go ahead and boot reiser4 /dev/sda2 to /mnt/anywhere
16:11.36yebyenand mount -o rbind /dev /mnt/anywhere/dev
16:11.47yebyenand chroot /mnt/anywhere, mount /proc, /sys, /boot
16:12.00yebyenlaunch x11 :)
16:12.05yebyeni think it's ok this way
16:12.20yebyenif i can't fix it, no big loss, i just need to get a new card/stick to boot from later
16:12.22Wizardhave you considered to resign from initramfs?
16:12.38yebyeni have considered that, i've also read threads that say reiser4 needs to be in kernel
16:12.57yebyenwhich i am doubtful of
16:13.06yebyenand something in update-grub signals to same effect
16:13.11Wizardyeah, in case of resigning from initramfs - it has to
16:13.14yebyenbut without fingerpointing at the filesystem
16:14.16yebyen*particular filesystem in question
16:15.10yebyenit's funny that x11 works ok
16:15.15yebyenthis is the one feature i could not make work using lxc
16:15.24Wizardmatter of root=blah kernel option in grub
16:15.44Wizardbtw, good, old lilo is nicer in such custom setups
16:15.50yebyenit says root=/dev/sda1, also tried with root=LABEL=Squ-20110222 and root=... other stuff
16:16.13Wizardeh..
16:16.13yebyenit's definitely not a problem of grub, grub can pick up the kernel just fine from the /boot that was made with reiserfs
16:16.27keyrayebyen: If you have boot problems try to play with the init boot kernel parameters, specially with APM and ACPI parameters: http://www.kernel.org/pub/linux/kernel/people/gregkh/lkn/lkn_pdf/ch09.pdf Also try to boot from usb
16:16.30Wizardyeah, it does :(
16:17.09yebyenit will be neat to pick apart the initramfs
16:17.16yebyenand see why it can't mount the reiser4
16:17.17Wizardi agree
16:17.28yebyenbut on a faster computer, for sure
16:17.31yebyenlol
16:17.36Wizardbut you will need to rebuilt kernel
16:17.37yebyenwith more keyboard and screen real estate
16:17.53Wizardand compile-in reiser modules
16:18.19yebyeni am looking at x11 now, i think i could just compile e17 and be just as happy...
16:18.32yebyeneven if it's in a chroot
16:19.20yebyeni think since the host system is not running hal, i can run hal and dbus in chroot no problem
16:19.41Wizardyup
16:20.11Wizarddid that on old notebook with broken hd controller
16:20.14yebyensometimes i find defective software and think it must be this way on purpose
16:20.31yebyento expose the system's naugty bits
16:20.52yebyen"yes there's actually a curtain here..."
16:24.30yebyenWizard: workin on anything cool?
16:27.29*** join/#elive _reid (~reid@pool-74-99-195-149.chi01.btas.verizon.net)

16:34.35yebyenmap[string]string{"foo":"bar} dude
16:34.41Wizardo_O
16:34.52yebyenoh no compilation error
16:36.11yebyeni was having an argument about closures with someone who said you don't really need them
16:36.18yebyenor something like that
16:36.34Wizardwhat's a closure?
16:36.34yebyenand i ended the fight calling him a wizard
16:36.42Wizardhey!
16:36.46yebyenlol
16:37.02yebyena closure is a lexical scope bound to a function
16:37.20Wizardsome go specific thing?
16:37.32Wizardmaybe i just don't understand the word ;P
16:37.36yebyenlike in { var x; func thefunc() { x=1 } }
16:37.51yebyenonly you don't do it that way
16:37.52yebyenoops
16:38.19yebyenvar y = func thefunc() { x = 1; } }
16:38.34yebyenthen later y()
16:38.39yebyenyou can do it in javascript too
16:38.58yebyenor ruby, python for that matter
16:39.09yebyendo you understand the code?
16:39.10Wizardpython calls it lambdas
16:39.12Wizardyup
16:39.13yebyenright
16:39.22Wizardnaaah, you could start with that :D
16:39.23yebyenand php 5.2 has it
16:39.31Wizardand java7 won't have it
16:39.41yebyenbut php 5.2 has a poor man's lambda
16:39.48yebyencreate_function($string)
16:39.52yebyenor,
16:39.52Wizard:D
16:40.07yebyencreate_function($args,$string)
16:40.09Wizardeval "dupa"
16:40.32yebyenand it doesn't inherit the local scope at all
16:40.57yebyensince php 5.2.14 you can do $x=function() { statements;}
16:41.06yebyenwhich is later than what's in lenny
16:41.12yebyenimportant because squeeze just was released
16:41.28Wizardi haven't written any php code
16:41.29Wizardever
16:41.33yebyenlucky
16:41.40yebyeni wish i would find a different job
16:41.56Wizardalso, any code in damn c#
16:41.58Wizard:>
16:42.15yebyenso mplayer is almost installed on my reiser4 root

19:25.55yebyenWizard: i figured it out, reiser4 modules are not really in initramfs
19:26.09yebyenWizard: modprobe was silently failing
19:26.10keyrayebyen: to use more than 4 GB of ram in elive, go to the nurse mode and install the special kernel
19:27.57yebyenat least i think i figured it
19:28.09yebyenupdate-initramfs will hopefully do the right thing now
19:30.28yebyenno complaints mounting rootfs!
19:30.30yebyenwoohoo
19:32.40Wizard:)
19:32.42Wizardcool
19:32.45Wizardi gave up
19:33.14Wizardi figured out only that if i remove password parsing it works :/
19:35.25yebyenpassword parsing?
19:35.31yebyenlike, to check for strong passwords
19:48.17Wizardyebyen: yup, that kind of things
19:48.33Wizardi don't understand that at all :(
19:56.32AlexAnteMachinaWizard, dont cry.
19:56.47AlexAnteMachinaI dont understand it, too.
20:09.45Wizardi don't cry
20:10.03Wizardi only wanted to say "fuck!" pretty loud
20:10.14Wizardso jboss architects would hear that
20:11.06Wizardwhy there is no option to pass additional params to jaas from WebAuthentication?!
20:11.16Wizard(with no hacking, of course)
20:27.53AlexAnteMachinawell, maybe you should do some sports.
20:28.06AlexAnteMachinaworkout makes a good mood
