I=E2=80=99m not sure = how to proceed otherwise. My guess is that if the release/tools/arm.subr line: chroot ${CHROOTDIR} gpart add -t freebsd-ufs -a 64k = ${mddev}s2 was instead (note the added -b use): chroot ${CHROOTDIR} gpart add -t freebsd-ufs -b 64k -a 64k = ${mddev}s2 then the line: chroot ${CHROOTDIR} newfs -U -L rootfs /dev/${mddev}s2a would work as expected and things would still be aligned: no aliasing of BSD vs. freebsd-ufs. (In part this is by prior steps already having achieved alignment of BSD.) But I do not know how to classify doing so: Work around? Known required-procedure for -L rootfs to correctly identify the the freebsd-ufs /dev/${mddev}s2a ? Absent better information from folks that know more, I'd suggest trying such an adjusted release/tools/arm.subr next week, leaving kern.geom.part.mbr.enforce_chs=3D0 in place, if such an experiment can be reasonable. > Glen > Sent from my phone. > Please excuse my brevity and/or typos. >=20 >> On Aug 7, 2022, at 12:10 AM, Mark Millard wrote: >>=20 >> =EF=BB=BFThe oddities look like indicated below. >>=20 >> # mdconfig -u md1 -f = FreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20220805-e24c5c60d72-257129.img >> # gpart show >> . . . >>=20 >> =3D> 63 10485697 md1 MBR (5.0G) >> 63 1985 - free - (993K) >> 2048 102400 1 fat32lba [active] (50M) >> 104448 10381312 2 freebsd (5.0G) >>=20 >> =3D> 0 10381312 md1s2 BSD (5.0G) >> 0 10381312 1 freebsd-ufs (5.0G) >>=20 >> =3D> 0 10381312 ufsid/62ed01f3345560d8 BSD (5.0G) >> 0 10381312 1 freebsd-ufs (5.0G) >>=20 >> =3D> 0 10381312 ufs/rootfs BSD (5.0G) >> 0 10381312 1 freebsd-ufs (5.0G) >>=20 >> So: ufs/rootfs apparently identifies the BSD instead of the >> freebsd-ufs .
