    Hi Aitor.

    I'm very happy that you cath up on Hopman. I initially made it for
my needs and the community and as a proof of concept. Then I became too
ambitious and I didn't succeed to properly organize internationalization
files and I got discouraged. Yet the tool is working and it is my only
installed tool to mount hotplug USB disks.

    The first method I considered to determine which device was
hotpluggable was a config file made of a list of regular expressions to
match the device file names, such as "sd[c-f]*", untill I found that
kernel tag. Then I discovered, like you, that it only tagged USB
devices. But I sticked with the kernel tag by lazzyness and beause I
could live with it (I use an USB-SDcard adapter).

    There is still a bug in a function in subdir watch, which I have
narrowed down to a logic error in the handling of multiple inotify
events in one buffer. This happens typically the first time a loop
device is mounted, because the driver then creates all loop devices at
once and the corresponding inotify events are small enough that more
than one can fit in the buffer; then hopman enters an endless loop.
Maybe I will dedicate time to repair it some day (~:
