[Bug 337492] New: grub update disables network boot
https://bugzilla.novell.com/show_bug.cgi?id=337492 Summary: grub update disables network boot Product: openSUSE 10.3 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: duwe@novell.com ReportedBy: ak@novell.com QAContact: qa@suse.de Found By: --- I have a system where i load the kernel from a server using grub (PXE doesn't work). For that I replaced stage2 with stage2.netboot Unfortunately an distribution update overwrites stage2 and then the network boot doesn't work anymore. The update should handle this somehow. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Experienced users (like you ;-) may at their own risk skip to the last section and supply relevant information right away. In this case I'd be particularily interested in your /etc/grub.conf -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Are you sure you need it? All I did was to copy over stage2 with stage2.netboot and then added an entry to menu.lst that booted over tftp. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

A grub update will install the new version into your configured boot path, discarding any undocumented one-time changes -> works as expected. hint: "info -f grub -n install" and then "vi /etc/grub.conf" -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Sure I can do all kind of things by hand (with the easiest being just copying stage2 over) but I'm trying to find a set up that is update safe My understanding is that a grub update will rerun grub-install and the network boot should still work after that. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
