Description Davide Pesavento (RETIRED) gentoo-dev 2007-07-05 14:03:45 UTC
Function stop() of init.d/fuse tries to unload kernel module even if there are some fuse-based filesystems still mounted, and it does not try to unmount them before doing so. Therefore localmount is not allowed to stop because it is needed by fuse which is still up. This results in localmount not stopping and so root filesystem is left mounted.

Two solutions come up to my mind:
1) init.d/fuse should not try to unload kernel module;
2) fuse-based FS must be unmounted before unloading kernel module;

Furthermore, if fuse script wants to remove the module, then it should be before localmount so that localmount can do the unmounting.

Reproducible: Always

Steps to Reproduce:
1. Mount a fuse-based filesystem
2. Reboot
3.

Actual Results:  
Root filesystem is not unmounted and is unclean at next boot.

Expected Results:  
/ is cleanly remounted read-only during shutdown phase.

TBH, I completely miss the purpose of the initscript. What's it good for? Kernel takes care of loading the module; what's the mount used for? Never used/needed it, everything works just fine.

I agree with you... a third option would be to completely delete the init script. In its actual form it serves no purposes IMHO (apart from breaking shutdown sequence and leaving me with a dirty filesystem).

have just dropped the unloading for you, FIXED
