About grml bootid
by T o n g 23 Jul '10

23 Jul '10

Hi, Can somebody explain the newly introduced bootid option? I know, bootid is used "for verifying the ISO through bootid=.... bootoption" and the logic behind bootoptions and possible combinations: * bootid.txt + wrong bootid=... => fails to boot * bootid.txt + right bootid=... => boots * bootid.txt + ignore_bootid => boots * bootid.txt + no bootid=... + no ignore_bootid => fails to boot * no bootid.txt + no bootid=... + no ignore_bootid => boots * no bootid.txt + bootid=... => fails to boot * no bootid.txt + ignore_bootid=... => boots I mean to ask, - what exactly does the bootid stand for? - how does the file /conf/bootid.txt generated? - how would bootid work with integrating multiple-grml on the same USB? Is there somewhere to read more about it? Thanks -- Tong (remove underscore(s) to reply) http://xpt.sourceforge.net/techdocs/ http://xpt.sourceforge.net/tools/

HD write protected and grml rescue mode
by T o n g 27 Jun '10

27 Jun '10

Hi, I get HD write protected warning when launching testdisk. As the aftermath, testdisk can't update the MBR: write_mbr_i386: starting... Store new MBR code file_nopwrite(4,1,buffer,0(0/0/1)) write refused write_all_log_i386: starting... write_all_log_i386: CHS: 9436/0/1,lba=151589340 file_nopwrite(4,1,buffer,151589340(9436/0/1)) write refused I never have such hard disk being write protected warning/error before. How can I fix it? Is it because of I'm running grml in rescue mode? Thanks -- Tong (remove underscore(s) to reply) http://xpt.sourceforge.net/techdocs/ http://xpt.sourceforge.net/tools/

grub2 loopback feature
by Alexander 'Leo' Bergolth 25 Jun '10

25 Jun '10

Hi! I'd like to use the loopback feature of grub2 to boot a grml iso-image that resides on a USB drive. Is there a way to make grub jump to the existing /boot/grub/grub.cfg in the ISO and show its contents as a submenu? I am thinking about something like: /boot/grub/grub.cfg on USB drive: -------------------- 8< -------------------- menuentry 'GRML' { iso_path=/iso/grml_2010.04.iso bootid=grml201004 export iso_path export bootid loopback loop $iso_path set root=(loop) configfile /boot/grub/grub.cfg } -------------------- 8< -------------------- Unfortunately, when selecting the menuantry above, my box reboots. When trying the same on the grub commandline, it reboots at "set root=(loop)". So root=loop doesn't seem to be supported... On the other hand, "configfile (loop)/boot/grub/grub.cfg" perfectly jumps to grmls boot menu. But when using this approach, I guess some support in grml's grub.cfg would be needed so that grub can correctly locate the image files. (Maybe a $loop variable prepended to all filenames in grmls grub.cfg, which is conditionally set to "(loop)"?) Any other hints?

grml2usb installation structure consideration
by T o n g 19 Jun '10

19 Jun '10

Hi, I've just submitted a feature request named grml2usb installation structure consideration at http://bts.grml.org/grml/issue874 I'm soliciting your comments are a normal user. Here is the repost of the content of the feature request. Currently, grml2usb install to the destination pen drive with the structure like this: . . . ./live/grml-medium/grml-medium.squashfs ./live/grml-medium/filesystem.module ./boot/release/grmlmedium/linux26 ./boot/release/grmlmedium/initrd.gz ./boot/syslinux/defaults.cfg ./boot/syslinux/grml.png ./boot/syslinux/hd.cfg ./boot/syslinux/isolinux.cfg ./boot/syslinux/grml_medium_default.cfg . . . I.e., every aspect of boot component has been seamlessly mingled into proper places. This is one way to arrange things, proper things go to their respective proper places (referred as plan-A afterward). However, I hope that the installation structure can take another approach -- all files go into a single directory, say /os/grml-medium-2010.04/ for example (referred as plan-B afterward). Here is my view of plan-B and plan-A: - directory structure. plan-B: self contained. plan-A: complicated, distro-specific related files spread arosss multiple directories. - organization: straightforward vs mixed-up. Use /boot/syslinux/ for example, plan-B contains only files originally from syslinux, nothing else, whereas plan-A contains files from all different flavours. - management: easy vs hard. Use deleting a flavour for example, plan-B just need to use a single command to remove (/os/grml-medium-2010.04/); plan-A: so complicated to do it manually that it is better to write another script to do it. - cooperate ability. relaxed vs strict. For example, when I want to try a new grml (beta) release, plan-B allows me to try it out parallel at /os/ grml-medium-newdate/ via for plan-A, the only way is to overwrite the version that I've been accustomed to and left with something risky. Please consider, Thanks -- Tong (remove underscore(s) to reply) http://xpt.sourceforge.net/techdocs/ http://xpt.sourceforge.net/tools/

Hi, How to do bug report from grml-medium? I mean, I can't paste into link2, and I don't want to re-type everything character by character. Does anyone know some small-footprint browser that can let me paste into web forms?

Right, it's not entirely correct. If you close multiple grml-chroot instances in the wrong order you will experience mountpoints from grml-chroot not cleand up. And get the appropriate error messages. Though your patch destroys _every_ other grml-chroot instance running in parallel because you just unmount filesystems which are in use. greets, michael
