This is a modified installer for Entware, a lightweight package manager and software repo for embedded devices.
If you'd like to install reMarkable specific packages, you should install Toltec instead, which includes the Entware repositories.
Connect the reMarkable via USB and make sure it has internet access.
Connect to the reMarkable with SSH and execute
wget -O - http://raw.githubusercontent.com/Evidlo/remarkable_entware/master/install.sh | sh
All entware data is located in
/opt (which actually points to
/home/root/.entware because of size constraints on the root partition). Base installation is ~13MB.
opkg install git opkg find '*top*' # search package names and descriptions
After a reMarkable update
reMarkable updates wipe out everything outside of
/home/root. While Entware remains intact in
/home/root/.entware, the mount over
/opt has to be recreated with
wget -O - http://raw.githubusercontent.com/Evidlo/remarkable_entware/master/reenable.sh | sh
No space left on device
You can clean up logfiles which take up considerable space on the root partition.
