Thanks for the crash course in Linux, DrYak. I would love to get this running (I can't stay forever with my N8), so this is the time to learn some Linux... Did I mention that an old 1GB microsd was recognized correctly by Sailfish?

Entering "mount" brings nothing with "/dev/mmcblk1"

Entering "[nemo@Sailfish ~]$ mount | grep mmc" brings:
/dev/mmcblk0p13 on /dsp type ext4 (ro,nosuid,nodev,noatime,data=ordered)
/dev/mmcblk0p25 on /persist type ext4 (rw,nosuid,nodev,relatime,nodelalloc,errors=panic, data=ordered)
/dev/mmcblk0p3 on /firmware type vfat (ro,relatime,uid=1000,gid=1000,fmask=0337,dmask=02 27,codepage=437,iocharset=iso8859-1,shortname=lower,errors=remount-ro)
/dev/mmcblk0p28 on /odm type ext4 (ro,relatime,data=ordered)
/dev/mmcblk0p52 on /fimage type ext4 (rw,noatime,data=ordered)
/dev/mmcblk0p28 on /opt/alien/odm type ext4 (ro,relatime,data=ordered)

Entering "[root@Sailfish nemo]# mount /dev/mmcblk1p1 /mnt/sdcard/" brings:
mount: mount point /mnt/sdcard/ does not exist

Entering "blkid /dev/mmcblk1" => Nothing happens:
[root@Sailfish nemo]# blkid /dev/mmcblk1
[root@Sailfish nemo]#

Entering "[root@Sailfish nemo]# lsblk /dev/mmcblk1" brings:
lsblk: /dev/mmcblk1: not a block device

Entering ""journalctl --since '5 min ago' " brings still a lot, somehow the following sticks out:
