в связи с завозом в netbsd 10 (current) поддержки udf 2.50 для makefs/fsck решил собрать утилитки под Linux/termux
https://github.com/Randrianasulu/fsck_udf https://github.com/Randrianasulu/makefs_termux
оно вроде собирается и даже работает, но на моей Франкенслаке почему-то падает fsck. Разработчик любезно глянул в мой хак, и лог gdb но там похоже что-то не инициализируется нормально - я могу обойти краш но при этом fsck начинает ругаться на файл образ созданный makefs…
кто-нибудь может собрать на разных линуксах и попробовать создать образ
makefs -o v=2.50,V=2.50 image.udf tree/
и проверить его?
fsck_udf image.udf
падает так:
(gdb) run ../makefs_termux-main/test.disk
