Hi, i stumbled over a problem in the handling of grub-mkrescue images on USB stick by Linux in /dev/disk/by-label.
The first MBR partition begins at 512-LBA 1 and thus is not mountable as ISO image. I understand this is intentional. ISO filesystems have a label (Volume Id) which gets used for auto-mounting and shows up in modern Linuxes as symbolic link in directory /dev/disk/by-label. But Linux (or its udev) insists in linking to /dev/sdX1 rather than to /dev/sdX, where the ISO filesystem is mountable. So this link cannot be used for mounting the ISO. I hate automounters, but /dev/disk/by-label is also a good way for a booting system to find its own filesystem from where it stems. ---------------------------------------------------------- Is a workaround known on Linux side ? (E.g. is it a known bug in udev configurations which can be fixed ?) How important ist the partition start at LBA 1 in comparison to this obvious drawback of grub-mkrescue images on Linux ? (Start at LBA 0 solves the problem but makes the MBR part of the first partition. I understand this is undesirable somehow.) Actually i wanted to show a system packager how to use ./by-label instead of test-mounting all files in /proc/partitions. Are there other methods which one could use in the Linux initial RAM disk to find the USB stick from where GRUB2 did boot ? Have a nice day :) Thomas _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
