I tried to make system with root on SD.
I installed system (OZ 3.5.3, GPE, SL5500) as usual, then copied all files to SD.
In /etc/rcS.d/01proot there is script mounting SD and changing root (pivot_root) to it.
Seems anything OK, expect I can't open terminal application and connect to my Zaurus over SSH. Syslog says that "can't allocate PTY". GPE works fine.
What is wrong?
