hello, is someone know how to launch a script when the oth is removed or installed ?
thanks

I dont know how it took so long to understand your post.

But I would like to know too. Maybe some day I find some use for it.

You can watch D-Bus for the signals and take actions on it. Look for com.jolla.tohd on the system bus.

ok, my jolla have a strange behaviour about sd card mount. it just DON'T automatically mount. but it's not a bad thing, because the default mounting point is not that good.

this is what i've done with my sd card:
mount:
/dev/mmcblk1 on /data/sdcard type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)
/dev/mmcblk1 on /home/nemo/Videos type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)
/dev/mmcblk1 on /home/nemo/Desktop type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)
/dev/mmcblk1 on /home/nemo/Documents type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)
/dev/mmcblk1 on /home/nemo/Downloads type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)
/dev/mmcblk1 on /home/nemo/Music type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)
/dev/mmcblk1 on /home/nemo/Pictures type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)
/dev/mmcblk1 on /home/nemo/Public type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)
/dev/mmcblk1 on /home/nemo/Templates type btrfs (rw,relatime,thread_pool=4,compress=zlib,ssd,noacl ,space_cache)

now, i want to unmount and mount my sdcard when i put the other half on and off, for not having a corrupt filesystem
