    <teythoon> the arg parsing in libdiskfs and libnetfs differ :/
    <teythoon> afaics libdiskfs gets it right, libnetfs does not
    <pinotree> what do you mean?
    <teythoon> wrt to *_std_{runtime,startup}_argp
    <teythoon> see eg netfs.h
    <teythoon> libdiskfs/opts-std-runtime.c:const struct argp
      diskfs_std_runtime_argp =
    <teythoon> libdiskfs/opts-std-runtime.c-{
    <teythoon> libdiskfs/opts-std-runtime.c-  std_runtime_options, parse_opt,
      0, 0, children
    <teythoon> libdiskfs/opts-std-runtime.c-};
    <teythoon> but
    <teythoon> libnetfs/std-runtime-argp.c:const struct argp
      netfs_std_runtime_argp = { 0 };
    <pinotree> well there are no common startup/runtime options provided by
      netfs
    <pinotree> usually netfs-based translators put netfs_std_startup_argp as
      child as their options, so if netfs starts providing options they would
      work
    <teythoon> ah
    <pinotree> if you have a test showing issues, we can certainly look it :)
    <teythoon> ok, m/b I was confused...
    <pinotree> no worries, feel free to ask anytime
    <teythoon> I thought about providing --update as common runtime flag, like
      diskfs does, you think it's the right thing to do?
    <pinotree> what would it do?
    <teythoon> or should it be left for each translator to implement?
    <teythoon> nothing by default I guess
    <pinotree> options provided in libdiskfs are implemented and handled mostly
      in libdiskfs itself
    <pinotree> so imho a new option for libnetfs would be there because its
      behaviour is implemented mostly within libnetfs itself
    <teythoon> libdiskfs calls diskfs_reload_global_state
    <teythoon> libnetfs could do the same, allowing translators to plug in
      anything they wish
    <teythoon> but I'll implement it in procfs for the time being
    <pinotree> ah, its alias is remount
    <teythoon> yes
    <teythoon> I need that working for procfs
    <teythoon> btw, I think I got your mount confusion thing figured out
    <pinotree> but procfs has nothing to update/flush, all the information are
      fetched at every rpc
    <teythoon> yes
    <teythoon> but we still need to ignore the flag
    <teythoon> otherwise the set_options rpc fails
    <teythoon> http://paste.debian.net/12938/
    <teythoon> whee, remounting proc works :)
    <braunr> :)
