Interesting. I haven't been using automounting, but I just enabled Xfce's native automounting (Thunar / Edit / Preferences / Advanced / Volume Management:Configure / Mount removable drives when hot-plugged) and stuck in a flash drive. It gets mounted and I don't see any FUSE involved: ~$ mount | grep sdb /dev/sdb on /media/<username>/disk type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2) ~$ mount | grep fuse fusectl on /sys/fs/fuse/connections type fusectl (rw,nosuid,nodev,noexec,relatime) portal on /run/user/1000/doc type fuse.portal (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000) I'm curious about this because I can't imagine that FUSE performance is as good as native, so why would automounters pay the performance penalty of FUSE when native mounting would seem easy enough to do?
