Frankly it's a very rooted way of programming, since C64 basic :-)
A part of this, how python catch variables, the longer the slower, isn't it?
Even supposing to use a set of similar name of variables.
Of course nowadays this operations ending up in term of msecs. I still be
used in old fashion. I'll change it by the time of necessity.

Great idea and common sense :-)

I like the clearer. I think python does it as we would think it off.

I found the bothering of having to remove the trailing LF "\n". Perhaps need
some new function to strip the last LF, for all of the files opened.

I wasn't able to handle more than one mount a time. Furthermore, the script
is executed every minute in a cron schedule. I don't expect to remove
devices in so fast fashion :-)
BTW, this operation is necessary because the kernel doesn't do it on its
own, for pendrives and Compact Flash into PCMCIA socket. (Kernel 2.6.15
actually)
One more point, suppose to use multiple removal, how will it remove also the
icon(s) from the KDE desktop?
Good to applying myself on studying on it :-)

A simple question, how do I'll get out of all loops, once found the right
result?
