[Touch-packages] [Bug 1817302] Re: growpart changes diskid of mbr disks
This bug was fixed in the package util-linux - 2.33.1-0.1ubuntu2 --- util-linux (2.33.1-0.1ubuntu2) disco; urgency=medium * debian/patches/32-bit-safe-mbr-parsing.patch: [PATCH] libfdisk: (dos) Use strtoul to parse the label-id. Thanks to Juerg Haefliger .

[Touch-packages] [Bug 1817302] Re: growpart changes diskid of mbr disks
On 32-bit sfdisk fails to parse the label-id if the MSB is set and thus generates a new one. We happen to be unlucky with our (i386) cloud image in that the original label-id has the MSB set. So when growpart run (which calls sfdisk), the disk ID is regenerated and subsequent boots fail because the kernel can't find the root device. ** Also affects: util-linux (Ubuntu) Importance: Undecided Status: New ** No longer affects: cloud-utils (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1817302 Title: growpart changes diskid of mbr disks Status in util-linux package in Ubuntu: New Bug description: When growpart is run against a disk with a dos partition table, it evidently changes the disk id in the MBR.
