Unfortunately, the -r option for mount(8) didn't change anything. I've tested that on the amd64 platform (at least in the USB installation media environment) everything works as expected and according to all manuals: # makefs -t udf -o disctype=dvdrom test.udf /tmp Calculated size of `test.udf' is 3104 KiB, 3 MiB, 0 GiB with 3 inodes Building disc compatible with UDF version 102 to 150 UDF properties 02004<REWRITABLE,READONLY> Volume set `6ae1ecbc1f1cf35a' Primary volume `16ce653f` Logical volume `anonymous` Total space on this medium approx. 2528 KiB, 2 MiB Recordable free space on this volume approx. 1888 KiB, 1 MiB /tmp/gettytab /tmp/sysinst.trem # vndconfig vnd0 test.udf 2048/1/1/0 # mount -t udf /dev/vnd0a /mnt # ls /mnt gettytab sysinst.term So the problem must be in arm64 specifics. Thanks, Iskander
