I'm afraid I don't know the answer but I can give some pointers to the code so you can work out what's going on:
https://github.com/libguestfs/libguestfs/blob/master/fuse/guestmount.c This is the program that is supposed to parse the -o options from the command line. It adds them to a list of options (fuse_options) that are passed to the libguestfs mount_local_* APIs. You should be able to see the arguments being passed through to the API if you use guestmount -x https://github.com/libguestfs/libguestfs/blob/master/lib/fuse.c This is where the API gets implemented. It's supposed to only pass the options through to fuse_opt_add_arg where fuse does the rest. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891906 Title: mount option does not work in guestmount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libguestfs/+bug/1891906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
