Also have to admit that I lost interest in UDF a bit, since we ended up looking towards hardware solutions for write-protections instead. But when/if mkudffs includes an option to create a write-once / read-only filesystem while adding files to it at the same time (because how else am I gonna put files onto my read-only filesystem?), then it might become interesting again. - Roald Den 01/08/2019 kl. 10.44 skrev Pali Rohár: > On Thursday 01 August 2019 09:35:30 Jan Kara wrote: >> On Fri 12-07-19 12:02:24, Pali Rohár wrote: >>> Also in git master of udftools has mkduffs now new option --read-only >>> which creates UDF image with Read-Only Access Type. >> I've tested this and the kernel properly mounts the image read-only. > Roald, can you test that problem which you described to me with > read-only access type is now correctly fixed? >
