I remembered incorrectly about chflags. It's not a single immutable flag, but several (depending on the OS). The owner or superuser can modify UF_IMMUTABLE, UF_READONLY, and UF_NOUNLINK. The SF_* flags can only be unset by the superuser in single-user mode.

We may not have CAP_LINUX_IMMUTABLE, but we can at least try to clear the immutable flag, no?
