Excuse me for double sent, but I forgot the attachment :( After upgrade from FreeBSD 12.0 to 12-STABLE of embedded image under BHyve guest I faced with bootloader issue.
>From FreeBSD 12.1 till current version of FreeBFrom FreeBSD 12.1 till current >version of FreeBSD. userboot.so loader haves issue with raw BSD partitions >directly on disk without any PC slice schema aka MBR or GPT. Bug came after commit, when predefine constant values was replaced with macro definitions in userboot/main.c and common/disk.c. These two members of devsw structure d_slice and d_partition now have defined constants. One of them have different value from previous version of code. D_PARTWILD now have value -2, before that change dev.d_partition has 0. I didn't take easy step directly to change macro D_PARTWILD to 0, because I saw that uboot loader already used this macro. I made patch in common/disk.c file into disk_open() functionSD. userboot.so loader haves issue with raw BSD partitions directly on disk without any PC slice schema aka MBR or GPT.
