Hi Alex,

Yes, bash will not remember paths across reboots.

Bash optimizes lookups on the PATH; having found an executable on PATH
once, it can remember that location for a minor speed boost.  The only
problem with this is that the cache can go stale.

>From what I understand remembering locations is usually done manually by
running =E2=80=9Chash=E2=80=9D.  I don=E2=80=99t know what would trigger th=
is behaviour in your
case.
