Editing init.x86.rc on Android x86

Can anyone offer me some guidance for making persistent edits to init.x86.rc on an Android x86 system (that I'm running in VMware)?

If I'm not mistaken, on a standard Android installation I'd need to unpack, edit, and repack the boot partition (boot.img), but I'm having trouble figuring out how to do that with Android x86.

Running cat /proc/mounts returns:

Code:

---

tmpfs / tmpfs ro,relatime 0 0
/dev/block/sda1 /system ext2 rw,relatime,errors=continue 0 0
tmpfs /cache tmpfs rw,relatime 0 0
/dev/block/sda1 /data ext2 rw,relatime,errors=continue 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
debugfs /sys/kernel/debug debugfs rw,relatime 0 0
none /acct cgroup rw,relatime,cpuacct 0 0
none /sys/fs/cgroup tmpfs rw,relatime,mode=750,gid=1000 0 0
tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
pstore /sys/fs/pstore pstore rw,relatime 0 0
/dev/fuse /mnt/shell/emulated fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0
none /proc/sys/fs/binfmt_misc binfmt_misc rw,relatime 0 0

And running cat /proc/partitions returns:

Code:

Does Android x86 not use individual partitions for boot, root, home, etc.?
