[fuse-devel] mount.fuse command line options

[Arthur v. D. <sou...@av...>]

Hello all,

In the Unanswered Questions section in the Wiki there is the question to
pass fuse helper script options from fstab. I think I've found a way to
implement this, without breaking existing configurations.

My configuration, which triggered me to solve this, is to automount an
encrypted directory using fuse.encfs. The password for the encrypted
volume can be supplied by an executable which is indicated by the
--extpass option to fuse.encfs. (That the password is stored on this
system is not an issue, the encrypted directory is to be protected when
stored off-site)

The current mount.fuse usage says:
  mount.fuse source destination -t type [-o opt[,opt...]]
Every option given is added to the -o opt,opts list passed to the
mount.type command.

I modified the mount.fuse source code so the options provided can be
treated in two ways. Options without starting dash are added to the
comma-separated options list as normal. Options with a starting dash are
added to the command line as separate command line parameters.

This way I can provide the necessary command line options for
mount.encfs on the options list of the autofs configuration. Haven't
tried it, but options in fstab should be possible now too.

I've made a fork in sourceforge, see
http://sourceforge.net/u/afvandongen/fuse/ci/master/tree/ . The only
file I changed is util/mount.fuse.c, the diff can be found under
http://sourceforge.net/u/afvandongen/fuse/ci/master/tree/util/mount.fuse.c?diff=e6e7a249c5c70187144dd9cd3767801ed05a1763

Please have a look at it, any feedback about this idea and my
implementation is welcome.
