The comment @Patrick made to your question was dead right: all the client machine needs to bootstrap PXE is to broadcast a DHCP request. The DHCP server (usually on the PXE boot server) will see the MAC address of the client device and will use it to give the client an IP address tell the client what files it should get from the PXE server at that point, ...

I found a case when I tried to use gummiboot instead of grub. Gummiboot reported error, that it cant find kernel images. It looks like I mounted /boot and configured fstab after I installed base system with pacstrap -i. So kernel images, that were placed in a /boot directory were lost after mounting and thus system could not boot. I wonder what happened with ...

I'm most familiar with how Cobbler sets up TFTP so I'm not sure if this is relevant but I'll offer this info up anyway. Cobbler sets up a bootloader using pxelinux.0 as @Patrick explains in the comments as well as @msw. But it also sets up a corresponding pxelinux.cfg/ directory along side it that contains MAC addresses for each system that will be ...

Files in /etc/network/if-up.d already run automatically whenever an interface (any interface) comes up. When you specify the same script to run again in an explicit post-up command, you only cause the script to run again. So my guess is this is what should happen: It runs once when lo comes up (with environment variable IFACE=lo) due to being located in ...

Delete empty line before post-up-command. This should relate the post-up command to eth0 only. Additionally move your script out of if-up.d folder. Scripts in that folder are executed automatically, no matter if defined as post-up. In your case it will run additionally to your post-up-command.

This is more of a windows question than an unix one, but heres how you can recover the windows bootloader: Boot into a Windows 7 install or recovery disk. You should be able to find a recovery iso online or on the Microsoft website. Once in, open up a command prompt and run the following: bootrec.exe /fixmbr This will reinstall the Windows bootloader, and ...

The biggest deficiency that LILO had was it didn't know anything about filesystems. It stored a static list of where the disk blocks holding the kernel were on disk. Same with the initial ramdisk image. The upshot of this is that that if you rebuilt your kernel or initial ramdisk, you had to remember to re-run the lilo command even if the files kept the ...

Simple things are often the best, but they lack the features from more complex tools that are sometimes useful. If you don't use those features, the extra documentation you have to wade through and things you can do wrong is a disadvantage. This applies to lilo vs. grub as well as to many other software (sed vs awk, C vs C++ (especially the newer versions ...

In looking through the manual it only seems to pertain to theming. This excerpt had a bit more on the subject. excerpt - http://www.gnu.org/software/grub/manual/grub.html#menuentry The boot menu where GRUB displays the menu entries from the “grub.cfg” file. It is a list of items, where each item has a title and an optional icon. The icon is selected ...

To find out how long it takes for the system to boot, systemd provides systemd-analyze. Without parameters, it will tell you the time to boot. Calling systemd-analyze critical-chain will print a tree of the chain of services that took the longest, while systemd-analyze blame will tell you how long each service took independently. Finally, systemd-analyze ...

Was an UEFI configuration problem, Hitachi SMP blades with more than 1TB of RAM need some tweeks. (Firmware dependant, so if you have such problem, ask Hitachi for the correct parameters).
