[Bug 357290] New: 'yast2 bootloader' module rewrites grub generic code when leaving with no changes, which may corrupt grub
https://bugzilla.novell.com/show_bug.cgi?id=357290 Summary: 'yast2 bootloader' module rewrites grub generic code when leaving with no changes, which may corrupt grub Product: openSUSE 10.3 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: YaST2 AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: root@proximasociale.cz QAContact: jsrain@novell.com Found By: --- i needed to reinstall my 'fallen into heresy' windows and then i'd needed to restore grub bootloader. I tried at first stance opensuse 10.3 install dvd, because i'd read somewhere, that it supports bootloader restoration. so, I'd found relevant section (install-methods->other->expert-tools->bootloader-restoration ..), but there i faced to some error, nothing was written to disk. I rebooted then into knopix live cd and :: mkdir /mnt/boot mount /dev/sda2 /mnt/boot ## i have separated boot partition grub-install --root-directory=/mnt /dev/sda ## 'chroot' is not neccessary << i'd rewrited generic grub code into mbr, using suse settings (original by yast created menu.lst is then used).. Everything was ok, but one thing changed. I lost default suse "boot-theme" and it was replaced with 'old-style' grub design. I'd launched 'yast2 bootloader' for check, how it things about my restored grub and if i could there rewrite grub again, which will result into 'original distributed suse grub' .. i found there, that this is the same module as on install dvd, so i'd leaved with no changes this module via 'finish' button. It rewrites then grub, which resulted into corrupted bootloader and restoring it with knoppix again.. solution:: order grub to do not rewrite bootloader code, if no changes are made. Best Regards ps. if u need logs, i forgot command for storing that (y2logs or something similar), so remind me it. -- 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.

I really like linux and suse, but i generally avoid of yast, because when i try it, then it will make more damage then good. This is very good example of (in my opinion) yast baffling and dangerous behaviour .. ie:: why it rewrites something when no changes made?? And why that corrupts some component? because at first stance :: reinstalling grub while every finish of that module is not very smart.. -- 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.

It survives some changes, but many not. Base options can be parsed correctly, but some additionals corrupts samba (or better said, yast corrupts samba if can not handle with that additionals) and nothing matter, that especially this module has "included-editor" for this kind of options.
