Comment (by idefix):
I tried to mount an partition in Linux (Ubuntu 11.10) as a normal user,
but it wouldn't let me:[[BR]]
With hrev41257:
{{{

When mounting an image, it would let me do it as non-user though.[[BR]]
With hrev41257:
{{{
jeroen@Gromit:~/Builds/Haiku/befs_fuse_bug$ mkdir bfs_fuse_mount
jeroen@Gromit:~/Builds/Haiku/befs_fuse_bug$ ./bfs_fuse_hrev41257 haiku-
nightly.image bfs_fuse_mount
bfs: mounted "Haiku" (root node at 131072, device = haiku-nightly.image)
jeroen@Gromit:~/Builds/Haiku/befs_fuse_bug$ umount bfs_fuse_mount
umount: /home/jeroen/Builds/Haiku/befs_fuse_bug/bfs_fuse_mount is not in
the fstab (and you are not root)
jeroen@Gromit:~/Builds/Haiku/befs_fuse_bug$ sudo umount bfs_fuse_mount
[sudo] password for jeroen:
jeroen@Gromit:~/Builds/Haiku/befs_fuse_bug$
}}}
But not with hrev43876:
{{{
jeroen@Gromit:~/Builds/Haiku/befs_fuse_bug$ mkdir bfs_fuse_mount
jeroen@Gromit:~/Builds/Haiku/befs_fuse_bug$ ./bfs_fuse_hrev43876 haiku-
nightly.image bfs_fuse_mount
bfs: mounted "Haiku" (root node at 131072, device = haiku-nightly.image)
fusermount: failed to open /etc/fuse.conf: Permission denied
fusermount: option allow_other only allowed if 'user_allow_other' is set
in /etc/fuse.conf
jeroen@Gromit:~/Builds/Haiku/befs_fuse_bug$
}}}
This is caused by the fuse option `allow_other`, which is - by default -
not allowed when mounting as non-root user.
I created [attachment:0001-Allow-non-root-to-mount-BFS-partition-with-
bfs_fuse.patch a patch] that will only set this option when the user is
root.
