Sooo, the only way to change the files in /opt/ would be to change the actual cramfs images in the flash, which seems to be doable during the firmware update process. I will investigate how it's done but I don't think I'll be brave enough to attempt the actual reflashing |
Another possibility is to create a copy of /opt on writable space, make the needed changes and remount it. Since no reflashing is involved the quota for bravery could be reduced, right?
