Fails to mount with "bad option" message

[Puuma]

A somewhat recent update broke the mountoptions, and now it doesn't recognize a bunch of valid mount options anymore.
I have this line in my cmtab
mountoptions=rw,nosuid,nodev,noexec,noatime,nodiratime,nobarrier

I have to remove the rw, nodiratime and nobarrier for it to work. Even tho those three are definitely correct and appropriate mount options in this particular use case.

I'm on Debian testing, cryptmount-6.4.0

Thanks for flagging this.
Internally, cryptmount prefers to use the mount executable if it's available, but has a fallback to the mount() system call. The latter supports a narrower range of mountoptions than /bin/mount. It's not obvious why the latest Debian build might be ignoring /bin/mount, but I'll do some more investigation.
Can you confirm that you're using the system-supplied version of cryptmount-6.4.0, rather than any custom-built version?
