https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=226536 Bug ID: 226536 Summary: glabel/partition mixup on sdcard images Product: Base System Version: CURRENT Hardware: arm OS: Any Status: New Severity: Affects Some People Priority: --- Component: arm Assignee: freebsd-arm@FreeBSD.org Reporter: trasz@FreeBSD.org The sdcard images distributed by the project contain two level (MBR/BSD) partition table. The root filesystem is mounted using UFS label, "ufs/rootfs". Problem is, the label gets attached to the wrong device: mmcsd0s2 instead of mmcsd0s2a. The result is that on first startup, only the first level of partition table gets resized, which can result in significant confusion when moving the SD card to another system. Looking at the image on another system (using md(4)), it looks like this: [trasz@brick:~]% gpart show [snip] => 63 6291393 md0 MBR (3.0G) 63 961 - free - (481K) 1024 34816 1 !12 [active] (17M) 35840 6255616 2 freebsd (3.0G) => 0 6255616 md0s2 BSD (3.0G) 0 6255616 1 freebsd-ufs (3.0G) => 0 6255616 ufsid/5a570a62577263b8 BSD (3.0G) 0 6255616 1 freebsd-ufs (3.0G) => 0 6255616 ufs/rootfs BSD (3.0G) 0 6255616 1 freebsd-ufs (3.0G) [trasz@brick:~]% glabel list [snip] Geom name: md0s1 Providers: 1.
