/dev/boot2 can presumably be written to to install a new boot2. THIS HAS NOT BEEN VERIFIED, DO NOT RELY ON THIS TO INSTALL A CUSTOM BOOT2.
This accepts the following commands: open, close, read, write, seek, ioctl, ioctlv
IOCTL example:
14 ioctl(0,4,12 return -101)
ioctlv 4,12,14 last only in IOS56+
/dev/boot2 IOS_Ioctlv
These ioctlvs do not seem to exist in IOS9; they may have been added later, or the person writing this may have been confused, since all 3 FS devices register to the same message queue.

/dev/boot2 error codes
Note: POSIX is a standardized system that helps maintain compatibility between many different operating systems. So, each error code shown below has a given POSIX equivalent (not known yet). Other OS's many have different error code numbers, but if their POSIX equivalent is the same, they mean the same thing.
| Error code | POSIX equivalent | Notes |
|---|---|---|
| -101 | ? | This can refer to: Invalid Wrong IN or OUT size, wrong size for a part of the vector, vector alignment problems, non-existant ioctl, or wrong structure. |
| -102 | ? | ? |
| -104 | ? | ? |
| -106 | ? | ? |
| -107 | ? | ? |
| -108 | ? | ? |
