Disk filesystem

Notice the shared libraries that must be present, and that we put all x86-specific files inside the /x86_64 directory, rather than directly at root:

[virtual=x86_64,uefi +compress] .bootstrap = {
  startup-x86
  PATH=/proc/boot:/bin
  LD_LIBRARY_PATH=/proc/boot:/lib:/dll
  procnto-smp-instr
}

[+script] .script = {
    devc-con &
    reopen /dev/con1

# Disk drivers
    devb-eide blk cache=2m,automount=hd0t179:/,automount=cd0:/cd &

# Wait for a "bin" for the rest of the commands
    waitfor /bin 10

# Some common servers
    pipe
    mqueue
    devc-pty &

# Start the main shell
    [+session] esh &
}

# Redirect console messages
[type=link] /dev/console=/dev/con4

# Add for HD support
[type=link] /usr/lib/libcam.so.2=/proc/boot/libcam.so

# Add symbolic links for bin, dll, and lib 
# (files in /x86_64 with devb-eide)
[type=link] /bin=/x86_64/bin
[type=link] /dll=/x86_64/lib/dll
[type=link] /lib=/x86_64/lib

# We use the C shared library, GCC's low-level runtime library,
# and the runtime linker.
libc.so
libgcc_s.so.1
/usr/lib/ldqnx-64.so.2=ldqnx-64.so.2

# Include the hard disk shared objects so we can access the disk
libcam.so
io-blk.so

# For the UDF filesystem
cam-cdrom.so
fs-udf.so

# Include a console driver, shell, etc.
esh
devb-eide
devc-con

In this buildfile, we see the startup command line for the devb-eide command:

devb-eide blk cache=2m,automount=hd0t179:/automount=cd0:/cd &

This line indicates that the devb-eide driver should start, then pass the string beginning with cache= (without the ampersand) to the block I/O file (io-blk.so). When the driver starts up, it:

1. Examines the command line passed to it.
2. Sets up a two-megabyte cache (the cache=2m instruction).
3. Automatically mounts the partition identified by hd0t179 (the first Power-Safe filesystem partition) as the pathname /hd.
4. Automatically mounts the CD-ROM as /cd.

Once this driver is started, we then need to wait for it to get access to the disk and perform the mount operations. The following line looks after the wait:

waitfor /bin 10
