I'm running 2.1.5. Maybe I "should" be able to write to it, but I can't... here's what happens:
Code:
[root@(none) /]# echo "the quick brown fox" > /mnt/sd/success.txt
-sh: can't create /mnt/sd/success.txt: Read-only file system
[root@(none) /]# echo "the quick brown fox" > /mnt/onboard/success.txt
