CentOS 7 support?
by Locane 11 Jun '15

11 Jun '15

Does anyone know if livecd-tools will support CentOS 7 at some point? Are there alternative LiveCD making tools that might run more reliably for creating a CentOS 7 LiveCD? I'm currently using livecd-tools to build CentOS 6 images for a PXE server, and it's been working ok, but I'm starting to get deprecation warnings and need to move up. Thanks in advance everyone.

naive user problems
by D. Hugh Redelmeier 28 May '15

28 May '15

[Every once in a while I try Live USB creator. I always seem to confuse myself and go back to dd. If I used it regularly, I'd probably be good at it.] I downloded Fedora 22, installed Live USB Creator, and tried to use it. I found the file selector awkward. It didn't show me the contents of directories until I insisted with some gesture I don't remember. I had a choice of Non-destructive or Overwrite. I had nothing I wanted to save on the stick, so I chose overwrite. And let it rip. Fine, but there was no Persistent Storage that way (for a reason I can guess at, after the fact). So I did it again with "non-destructive". After an hour, it is still stuck at 99% installing bootloader. My guess: there is no partition structure of (FAT) filesystem after dd'ing a .iso to the stick. Surely a diagnostic would be in order. It would be good if there was a "make a suitable FAT filesystem" choice.

Don't toss your FC21 Live CDs just yet
by ToddAndMargo 27 May '15

27 May '15

Hi All, The new Live DVD is now a DVD, not a CD. (Thank you guys!) If you are using Live CD to do maintenance on older computers, don't toss your FC21 Live CDs just yet. First make sure the target computers will boot off a DVD. :-) -T I must have typo'ed "live" as "lice" about three times. I hope I got them all corrected. It is not quite as embarrassing as typo'ing "Widows" for "Windows". :'[ -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Computers are like air conditioners.

boot issues follow up
by ToddAndMargo 22 May '15

Hi All, I have been using my "Dead Stick" (my wife's name for my direct install stick) in almost every customer's machine that I get a chance. So far, not a single computer has failed to boot. Yipee! (I did have to change a line in grub.cfg to use my UUID.) Wednesday it even booted perfectly in a Lenovo T510, which the live USB refuses. (Used my dead stick to remove a GPT partition on a G-Drive.) Since I used the exact ISO on the Dead Stick as the Live USB and the Live CD always boots, the problem I do believe is isolated to the Live USB creation procedure. And even though Red Hat "says" it will support EL 6 till 2020, they have stopped supporting things like this. See https://bugzilla.redhat.com/show_bug.cgi?id=1220107 So poop! (KVM is even a bigger pain in the neck with the loss of support on EL6) But, the dead stick boots faster than the live USB and I still have 70% of my 16 GB left over. (I even have Libre Office installed on it to show M$ customers that I can still retrieve their documents off a corrupted hard drive.) The stick is USB3, but so far I have only booted off USB2. I take than back, my shop FC21 is USB3 and oh did it boot like the wind. Yesterday, I yum'ed the printer config utility into the stick at a customer's site to print out a document and I used the nt reg utility to reset another customer's NT Admin password and get off a non-existent domain server. And I check another customer's SMART drive status. (Hard drive was fine: he had junkware.) And I have been transferring things off and on my stick to my base systems by mounting the sticks ext4 file system. It is so stinkin' convenient! This dead stick is so stinkin' useful I'd be here all day carrying on about it. Nobody got to see the bounding cows though. Rats. Everyone has been very decent and gracious helping me along to getting my Dead Stick working. Thank you, I sincerely do appreciate it. I took good notes, if anyone has a question. -T -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Computers are like air conditioners.

Direct install boot in one computer but not the other
by ToddAndMargo 19 May '15

19 May '15

Hi All, I am trying to install FC21 directly to flash drive. So far, I can get the flash drive to boot into both my computers if I use LVM file system. But, LVM is a pain in the neck to copy files to and from. So, I switched to normal partition. Problem: now the thing will only boot into the computer it was created on. The other one give me ERROR: dracut-initqueue[303] ln failed to create symbolic link /dev/resume already exists (I find no such file) /dev/sdc2 does not exist (which is my swap) Starting Dracut emergency shell I have no idea what is going wrong. Google is not helping either -T

Direct install?
by ToddAndMargo 17 May '15

17 May '15

Hi All, I am always having something go wrong with Live USB. I occurs to me that why don't I just directly install FC21 to a flash drive? Will this work and will it be bootable? (I use the Live CD to do installs, so I don't need that feature on a bootable stick.) Many thanks, -T -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Computers are like air conditioners.

USB 3 frustrations
by ToddAndMargo 16 May '15

16 May '15

Hi All, I made up a USB bootable Fedora Xfce flash drive. Seems to work just as well as the Live USB. And, it get around the problem with the small persistence and the worse problem of the persistence not giving back space when files are deleted. But I could get the bugger to boot in my Supermicro X8SAX based computer. Turn out that the X8SAX's BIOS doesn't see flash drives in my add on USB 3 controller: $ lspci | grep -i usb ... 09:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02) I boots perfectly when I moving the drive to a USB 2 port. -T And, it does boot perfectly in my other Supermicro C7Z87 based computer with a native USB3 controller

3 GB barrier
by ToddAndMargo 13 May '15

Hi All, Is there a reason why there is a 3 GB barrier on persistence with ext3? Am I just banging my head trying to figure a way around it? -T

livecd-tools naming convention?
by ToddAndMargo 12 May '15

12 May '15

Hi All, I have been looking at the different SRPMs for livecd-tools. It seems like the revision is also the same as the revision of Fedora. For instance: livecd-tools-19.10-1.fc19.src.rpm livecd-tools-20.1-1.fc20.src.rpm livecd-tools-21.5-1.fc21.src.rpm So, how does one tell what actual version of the software you are using?

persistence still doesn't work
by ToddAndMargo 09 May '15

09 May '15

Hi All, Persistence still doesn't work. I just opened up https://bugzilla.redhat.com/show_bug.cgi?id=1220015 I will quote it here: Dear Red Hat, I am coming from the community: Scientific Linux 6.6 x64. I am trying to create a Live USB with persistence. Would one of our intrepid heroes please fix this for me? The Stick is 16 GB. It is formatted as ext3. # rpm -qa livecd-tools livecd-tools-13.4.5-1.el6.x86_64 According to this: https://docs.fedoraproject.org/en-US/Fedora/10/html/Release_Notes/sn-Live_U… livecd-iso-to-disk --overlay-size-mb 512 /path/to/live.iso /dev/sdb1 "Replace /dev/sdb1 with the partition where you want to put the image. Replace 512 with the desired size in megabytes of the persistent data, or overlay. The livecd-iso-to-disk shell script is stored in the LiveOS directory at the top level of the CD image. The USB media must have sufficient free space for the Fedora Live image, plus the overlay, plus any other data to be stored on the media." This is my command line: livecd-iso-to-disk --overlay-size-mb 13287 Fedora-Live-Xfce-x86_64-21-5.iso /dev/sdc1 After booting off the Live USB, I get the following: df -kPT / Filesystem Type 1024-blocks Used Available Capacity Mounted on /dev/mapper/live-rw ext4 3030800 2431496 551468 82% / Means the persistence is set at the default of 3GB. Many thanks, -T

boot update?
by ToddAndMargo 09 May '15

09 May '15

Hi All, I have a cherried out Live USB I use at customer sites. It gives me a bad time booting on some systems, especially ones with Supermicro motherboards. HP always boots. Is there a way I can update the boot portion on the stick with the latest utilities to see if that helps? Or, do I have to wipe and start over? And, to do a back up in case things go wrong, can I use "dd" to backup and restore? Many thanks, -T -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Computers are like air conditioners.

Need help with space issues
by ToddAndMargo 09 May '15

09 May '15

Hi All, This is a 16 GB EXT4 FC21 Live USB with persistence. Not sure why I have run out of space: # yum install ntfsprogs ... Total download size: 574 k ... At least 2MB more space needed on the / filesystem. # df -kPT Filesystem Type 1024-blocks Used Available Capacity Mounted on /dev/mapper/live-rw ext4 3030800 3002320 0 100% / devtmpfs devtmpfs 1004556 0 1004556 0% /dev tmpfs tmpfs 1024748 68 1024680 1% /dev/shm tmpfs tmpfs 1024748 664 1024084 1% /run tmpfs tmpfs 1024748 0 1024748 0% /sys/fs/cgroup /dev/sda1 ext4 15264688 1562576 12903648 11% /run/initramfs/live tmpfs tmpfs 1024748 36 1024712 1% /tmp varcacheyum tmpfs 1024748 716772 307976 70% /var/cache/yum vartmp tmpfs 1024748 12 1024736 1% /var/tmp tmpfs tmpfs 204952 8 204944 1% /run/user/1000 Seems like I have space everywhere, except live-rw (which is always full). What am I missing and where do I go to make space? Is it time for a larger stick? Many thanks, -T -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Computers are like air conditioners.
