Zdravim,

som sa rozhodol, ze si trocha rozsirim obzory a jednak si myslim, ze je to najjednoduchsie riesenie a zaroven neinstalovat ine aplikacie, ktore ich ucelom je pripajanie zariadeni ako usb disky, karty a tak podobne. Takze prisiel rad na udev a jeho moznosti. Nasledovne pravidlo som si napisal, ale zial nefunguje. Pokial je tam iba jeden RUN, tak to ide, ale v pripade, ze su dva, tak uz nie a pritom som videl, ze ani viackrat pouzity RUN nerobi problem. Alebo je to problem ?

ACTION=="add", SUBSYSTEMS=="mmc", ATTRS{manfid}="0x000074", ATTRS{oemid}=="0x4a45", ATTRS{serial}="0x000001c1", ATTRS{type}="SD", RUN+="/bin/mkdir -p /media/sdcard_camcorder", RUN+="/bin/mount -t vfat %k /media/sdcard_camcorder -o defaults,users,noexec,noatime,iocharset=iso8859-1"

Pre ACTION="remove" mam nastavene odpojenie a nasledne vymazanie adresaru. Tu sa vsak natyka dalsia otazka a to, ako sa mysli to odstranenie (remove), pretoze ma napada, ze pokial by vsetky udaje neboli este zapisane, tak pri najlepsom scenare budu niektore data necitatelne. Mozno sa hlupo pytam, ale napr. pmount neodpoji disk pokial prebieha zapis, aj napriek tomu, ze cp, mv atd uz svoj beh ukoncil uspesne, no pokial ja kartu vysuniem, tak je to len otazka casu, kedy sa nieco take stane.

Este pridavam vypis z udevinfo:

 
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
