However, makefs' implementation of the TF record ignores a timestamp passed using the -T flag, making the resulting ISO image nonreproducible. This issue can be observed in the top-level directories by running 'diffosc= ope' on two 'bootonly.iso' images that have been built back-to-back with a fixed timestamp ('-T 1742574909'): | drwx------ 18 0 0 4096 2025-03-21 16:35:09.000000 . =E2=94=82 -drwxr-xr-x 2 0 0 6144 2025-03-24 14:48:55.00= 0000 bin =E2=94=82 --r-xr-xr-x 6 0 0 - 2025-03-24 14:48:55.00= 0000 bin/cat =E2=94=82 --r-xr-xr-x 6 0 0 - 2025-03-24 14:48:55.00= 0000 bin/chflags --snip-- | +drwxr-xr-x 2 0 0 6144 2025-03-24 14:57:38.000000 bin =E2=94=82 +-r-xr-xr-x 6 0 0 - 2025-03-24 14:57:38.00= 0000 bin/cat =E2=94=82 +-r-xr-xr-x 6 0 0 - 2025-03-24 14:57:38.00= 0000 bin/chflags The dot directory record has the appropriate timestamp set, but the rest of= the directories do not. --=20 You are receiving this mail because: You are the assignee for the bug.=
