CentOS 7, not systemd questions
Question 1: has anyone used preupgrade (I used it with fc 17 -> 19, and it pretty much appeared to work, but that was on a couple of worksttions)? Opinions? Question 2: is grub still supported, or is there something that *FORCES* you to use grub2? mark "grub2 must DIE!"

Bug#603391: Workaround PyGrub issue
Confirmed this issue. To reproduce: Install a fresh Wheezy AMD64 guest under Xen 4.1 (hypervirtualized, boot from the debian-7.1.0-amd64-CD-1.iso). Use "entire disk" automatic layout for partitioning, this creates /dev/xvda1 for / and /dev/xvda5 for swap. It will create /boot/grub/grub.cfg with many references to (/dev/xvda,msdos1) which works fine when the machine is booted

Centos 7, grub2-mkconfig, unsupported sector
Hi, folks, Well, I get back from vacation, and three CentOS 7 boxes didn't come up this morning (my manager and the other admin did the update & reboot). On these three - but *not* another one or two, and I don't think those others are Dells, they're supermicro's - the 327 kernel fell into the rdosshell, I guess. I finally got one the three up by going back to the 228.14

installer and os-prober not finding Windows XP installation
I installed CentOS 7 on a Shuttle X27D box (dual-core Atom 330), and so far it seems to work fine, but it didn't set up a Grub2 entry for the existing Windows XP installation in the first partition (MBR). Running os-prober generates no output. fdisk shows that the NTFS partition is still present as /dev/sda1, and still has the bootable flag set. I added a menuentry for Windows to the end of

GRUB2 configuration for Xen 4 on Ubuntu Linux 10.04
Hello, I have installed the Xen 4.1.1 and a working kernel 2.6.32.43 which supports Xen on a Ubuntu Linux 10.04 LTS. However, I have never successfully booted the Hypervisor and Dom0. The screen is always black after some kernel messages rapidly go by. I think that I may pass the wrong parameters to the kernel or Hypervisor with GRUB2. Can any one share his/her working grub.cfg for GRUB2 with

/boot as a btrfs subvolume
As of the latest updates to anaconda and grub2 for Fedora 18, it is now possible to install with /boot as a btrfs subvolume. The way that grub2 is handling this is the "reach down" to the files it needs as if the subvolume was a directory. Is this OK? At this point I am not worried about snapshots or any other complexities. If the subvolume name is known. should grub2 be able to

How does Live CD find OS's?
If I boot into CentOS on my home server from a Live CD or USB stick and go to Troubleshoot, it lists OS's it finds on the machine. How does it find these OS's? Presumably it looks through all the partitions on all the hard disks for something that looks like an OS? But how exactly does it identify an OS? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College,

installing C7 on a laptop with Win7, dual boot
Hi all! I've just installed C7 on my netbook that already contained Win7 (and also Fedora 19, which the C7 is intended to replace). The Fedora installer had found the windows installation and it appeared in the grub menu, and was bootable and worked fine. The C7 installer did not put the windows installation into the grub menu. with some googling I found a page at
