For the last year I've been meaning to read how systemd actually works. I hope it isn't actually another case of looking good on paper like launchd.

allquixotic

@ScottPack systemd is to sysv init as pulseaudio is to /dev/dsp

the analogy is quite striking; coincidence that the author of systemd and pulseaudio happens to be the same guy

Michael Hampton

@ewwhite DUPE!

ewwhite

@MichaelHampton where?

allquixotic

systemd: (1) replaces init, (2) replaces /etc/init.d startup scripts, (3) replaces basically the entire userspace boot sequence (which to date has basically been a collection of random shell scripts on most distros) with a program coded in C that is more error tolerant and robust, and much faster

@MDMarra How much does Casper Suite cost

@ewwhite I marked your question as a dupe.

ewwhite

@MichaelHampton I didn't see it.

MDMarra

@mossy it's not insignificant

David

@MDMarra general error code lol

mossy

holy shit that was loud

David

@MDMarra Error Code FFFFFFFE

@mossy i don't know what the list price is, I got quoted on .edu discount for a couple hundred machines

Jacob

Hi all

mossy

@MDMarra I'm watching the videos for the patch management system - would make things so much easier.

MDMarra

yeah

it's nice and it can manage iOS devices too

Really? You should call Red Hat and attempt to get your money's worth out of those subscriptions you're overpaying for. — Michael Hampton 38 secs ago

48GB SWAP a good idea?

@mossy What product are we talking about here?

@ewwhite what could possibly go wrong

Joel E Salas

@ewwhite Sounds good to me! Are you setting up Terracotta by any chance

Scott Pack

@allquixotic So long as it results in nfs entries from fstab being mounted after the network is up I'll be happy.

ewwhite

@JoelESalas lingering Oracle DB issue.

Joel E Salas

@ewwhite Is the lingering issue the fact that you're using oracle

@David You curse Microsoft, check the event log to see if there's any useful information and Google the error code/event log information to find the KB describing the pain-in-the-ass process by which you unfuck the update that involves uninstalling and reinstalling the .NET framework v[something] about half the time.

David

@HopelessN00b lol

HopelessN00b

Glad you're amused. By the time you've had to do that a few hundred times, it's significantly less funny.

allquixotic

@ScottPack It has explicit service dependency kind of like Windows' service control manager, so in that sense, it can definitely do that

it's also aware of things like "is the network actually up"

Joel E Salas

I feel like there's an internal timer inside every local git repo that is counting down to when you irreparably cock it up and have to nuke-n-clone or reset

allquixotic

@JoelESalas git stash

Joel E Salas

20:15

git stache

Scott Pack

@allquixotic Supposedly chkconfig does some stuff like that, but I don't think it's nearly as good about it.

Michael Hampton

@ewwhite You can try the other command to lock it at registration time, I suppose. Though really, you need to be talking to Red Hat at this point.

Chris S

Anyone know of a way to detect if your shell is running in a chroot??

Michael Hampton

@ChrisS Just guessing... ls -id /

allquixotic

20:23

Michael Hampton

I don't actually have a chroot environment handy!

Chris S

@MichaelHampton My chroot starts at a mounted filesystem, so low numbers. Also, zfs's / isn't always the same inode number.

Joel E Salas

whooaoaoaoa why not?

Chris S

why not what??

A: How do I tell I'm running in a chroot?

What I've done here is to test whether the root of the init process (PID 1) is the same as the root of the current process. Although /proc/1/root is always a link to / (unless init itself is chrooted, but that's not a case I care about), following it leads to the “master” root directory. if [ "$...

Chris S

20:26

@allquixotic Looks promising, if I had a /proc file system

Michael Hampton

@ChrisS Are you even using Linux?

Chris S

@MichaelHampton Nope, FreeBSD

I could enable procfs, but seems kinda silly to do that just to get the color of my prompt to change in a chroot

Michael Hampton

@ChrisS Oh god. Go ask a neckbeard.

allquixotic

@ChrisS X/Y. You don't have to detect whether you're in a chroot jail to change the color of your prompt.

Chris S

@allquixotic I want the color to automatically change when I enter the chroot...

allquixotic

20:29

@ChrisS how are you entering the chroot?

Chris S

@allquixotic chroot /jails/build

Michael Hampton

alias chroot...

allquixotic

if you spawn a bash sub-shell in the chroot jail, then it'll read from /home/<you>/.bashrc and/or /etc/profile in the jail

Chris S

@MichaelHampton Hrm; that's an idea

allquixotic

just set your PS1 variable appropriately in the jail

Chris S

20:31

@allquixotic Right. Was trying to be lazy and use the same rc everywhere. I've got one that picks up if the shell is jailed, but I haven't found a reliable way of picking up chroots.

HopelessN00b

Hmm. Question for you Windows/VMWare guys... how would you expand a system drive on a server 2003 VM?

Chris S

@HopelessN00b Expand in the virtualization system, boot WinPE and use diskpart to expand the file system; reboot

jscott

@HopelessN00b What Chris said, or shutdown the VM, mount the vmdk on another vm and use diskpart to extend.

Chris S

Then kick myself for the next 14 minutes for running a decade old OS

@jscott That's simpler yet, especially if you don't have WinPE sitting around.

HopelessN00b

@ChrisS Do you get any stability issues from doing that? I read something back in the day about Server 2k3 not playing well after having its system partition resized.

David

20:33

lulz, girl at italian restaurant must think i'm cute

asked how much for an extra piece of garlic bread and she hooked me up for free

Chris S

@HopelessN00b I've not had any problems with using diskpart. I know GParted will screw up system partitions. YMMV

jscott

@HopelessN00b I've done this a number of times with 2003 + ESX/ESXi, no issues.

HopelessN00b

Excellent. Thanks guys, will give that a shot. See how many production systems I can correct/implode/hasten an OS upgrade on.

David

@HopelessN00b support.microsoft.com/kb/976982 looks like you may be correct

jscott

@David Or she was trying to work a larger tip from you.

David

20:36

@jscott she knows i never tip, because take-out

jscott

@David cheapskate! :)

myotherpcisacloud.com: Signing Powershell Scripts

posted on March 08, 2013 by ryan

Hi guys, Something you might know about me is that I think Powershell is just about the best thing to ever happen to Windows Server. And even if you don't agree... well, you don't really have a choice because there are already tasks that must be done in Powershell and there is no GUI alternative, and that trend will only continue. Powershell will become part of your life if …

backing up vps to reinstall

Didn't use LVM when installing, and now I need to grow partitions (yay free upgrades)

they halved the price, added a second core, quadrupled the memory to 4G and tripled diskspace to 150.

Is @mdmarra around?

Dennis Kaarsemaker

@ewwhite he's probably still waiting for you to pay him :P

Matt Bear

man I should of started this transfer last night....

@Hennes damn it, dont give me somthing else to read up on!

Hennes

Heh.

Matt Bear

crap... im burnt out

@Hennes yeah... I dont think my brain can handle anything beyond Homer Simpson right now

Matt Bear

wish I could format/reinstall my head right now

upgrade the OS, add some more RAM

@Hennes Don't defrag too much, or you won't be able to stop remembering every time your dad wore a speedo.

@DennisKaarsemaker wouldnt that make things worse....

@MattBear maybe, but at least you won't realize it :)
