# --- Persistent learning state -------------------------------------------
|
||
|
|
# f()/fx() key learned fixes in a file called "p" in the current directory.
|
||
|
|
# On a plain live-CD boot that file lives on tmpfs and every reboot forgets
|
||
|
|
# everything the shell has ever learned.
|
||
|
|
#
|
||
|
|
# If a second, writable disk is attached (anything that isn't the boot
|
||
|
|
# CD), use it as a raw flat store for "p" -- no filesystem, no mkfs. This
|
||
|
|
# live image never mounts modloop-virt into /lib/modules, so modprobe has
|
||
|
|
# nothing to load and mkfs.ext4/mount fail with "Invalid argument"
|
||
|
|
# regardless of e2fsprogs being installed; dd/tr are busybox builtins and
|
||
|
|
# need no kernel module at all, so they work unconditionally. Learned
|
||
|
|
# fixes are restored from the disk's first 1MB at boot, and a background
|
||
|
|
# loop flushes "p" back to it every few seconds. No such disk -> "p"
|
||
|
|
# stays on tmpfs exactly as before.
