Lately I became fed with all the consolekit disturbances, and decided to finally get rid of it. It has already had its chance but failed misserably, and I am not going to engage into systemd, I have no need of that. So, I started to look for alternatives, and found udevil, which does many things. In first place, it can automount. And then, it allows for 'umounting' as a user. There are also many goodies, like mounting of ISO fs's, sshfs, ftp via curlftpfs and a few others.
It works very well with spacefm, which is another extra goodie that might come in handy (even though I rarelly use a GUI file manager).
The problem is was that, just like with the pmount+uam binomial, there's no frontend to udevil (other than spacefm, that is, and using a file manager just to mount disks doesn't seem to convenient).
