Re: Booting from a USB Drive
GOOD NEWS!!! I got it working. I can now boot on this external drive without having to jump start from a live cd and chroot or any of that. It seems that my mkinitcpio.conf did not include 'usb' as one of the hooks for building the initial RAMFS image. I figured the RAMFS was failing some how since the usb drive hadn't been formerly listed in the startup sequence. So I added usb to the list of hooks and she's working now. I don't know a whole lot about the insides of mkinitcpio or if this configuration is common accross most distros but I got mine working and I guess that's what really matters. Thanks to all of you for your helpful answers and ideas. Now off to fix my wireless challenge smile. --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
Re: Booting from a USB Drive
Fantastic! And where did you find this mkinitcpio.conf? Was that in Arch Linux? Did you look in any others (sounds like not yet)? And what did you have to do after adding the usb entry (like remaster an iso, or ...)? Larry On Wed, Dec 8, 2010 at 7:31 AM, Steve Holmes st...@holmesgrown.com wrote: GOOD NEWS!!! I got it working.

Re: The Sysadmin career field outlook
I would have to politely disagree with the previous 2 postings. I see a lot of sys admin jobs out there. But like any profession it is having the right skills at the right time. I think Linux admins with enterprise experience are in demand now. But the key is having a broad base of knowledge and choosing you speciality to match what you have talent for and what the market is looking for. I see the career path for the admin is moving up to system engineering and or then to IT management. For a good idea of what people are looking for in the market just start looking at all the jobs posted in the field you are wanting to get in to. That should give you a good idea of what skills they are generally looking for. Good luck!!

Re: The Sysadmin career field outlook
the old school JOAT it admin is still in need but mostly in museums and schools where you need more skills available and they cannot afford as much outsourcing/specialization, but this breeds its own difficulties as well. I see a number of positions of all flavors go by. but i think diversification in your skill set is more valuable than the industry makes it appear, because you get more opportunity that way. but many places are trying to cut payroll and outsource this, when in reality it can cause them more harm than good, but that is not something you can see in the short run, only in the long run. a solid combination is someone on site who can do it all, then bring in a specialist for a project to absorb that projects workload efficiently and then be able to understand what was going on to keep it running after it was over. but i think that diverted from topic a little. The sysadmin in a traditional sense is still there and very much in demand, but the market is such that they are not turning over allot right now. so the jobs are not as available. this will change some. for some of my previously stated reasons. and the market loosening back up On Wed, Dec 8, 2010 at 10:19 AM, Shawn Badger sh...@badger.pro wrote: I would have to politely disagree with the previous 2 postings.

Re: rsync help the gramma
You're pretty close to ideal there. I use rsync -avEHh --delete-after --progress $SOURCE $DESTINATION Generally no need to sudo for your own homedir, and -z is really only useful for network copying (it compresses in-transit, not on disk). That will only copy over changes between the source and destination, and will remove anything in destination that's no longer in source. Make sure the external drive is formatted EXT3 or XFS so you can preserve things like access controls and ownership. When you look at the final output of the command, there's usually a ratio listed. That's the amount that could be copied vs. the amount actually copied. If that's much larger than 1, then you're only copying changes. ==Joseph++ betty wrote: I have an ext hdd that i copy my stuff to every few months.

Re: The Sysadmin career field outlook
Yeah, I'm in the process of learning some new skills since mainframe software programming has gone to the pasture to be burried! I regret I didn't pick up and begin learning some of the newer technologies some years ago so no time like now to get started. I've been giving thought to sys admin work as a possible direction but then most of my experience so far has been in programming so figured it maybe more proodent to study newer languages like perl, python, php, wet dev, etc. It's an exciting time to go out and learn new stuff but it will mean an even longer time before I can really pay the bills the way I want. Thank God for Social Security Disability in the meantime. smile PS: I was laid off last spring so congrats on getting a new job in such a short time given this screwed up economy.

Re: rsync help the gramma
Yes, I commend you for going for the command line tools like that. Tackling rsync is no slouch by any means. Frankly, I can rarely remember all the command line options for rsync and have to either constantly look at the man page or previous working examples. I would also create little one or two line shell scripts with these commands in them and then just run the script each month or whenever. That's why Joseph's script example had the '$1' and '$2' thingies in there. those can then be substituted by just putting in the names of the paths and run the script. Also, I believe Joseph's example included the --delete option. However, I don't recall what is actually being deleted at that point. Might wanna check to be sure there. Also, if you get more adventuresome in the future, you might wanna look at a program called rdiff-backup. It uses rsync under the hood and allows for optional inclusions and exclusions like rsync does but allows for staging different backup sets over time and yes, each subsequent backup is just the differences. Plus then if you need to restore a file from the most recent backup, it is merely a mirror of your current environment so you can just copy the desired item to be restored. But rsync is a good start and an excellent way to sync up two computers over a network too. On Wed, Dec 08, 2010 at 10:18:01PM -0700, Alan Dayley wrote: Do not think yourself stupid!
