Description

a.k.a. the NOARP mystery

Some scripts rely on an assumption that cd $OLDPWD will change the current working directory to the one before previous cd. This is no longer true when the "previous cd" failed. $OLDPWD is then not updated so cd $OLDPWD takes the shell to some other (wrong) place. While current working directory is assumed to be invariant across certain scripts, a missing directory can cause some strange, seemingly unrelated problems.

To reproduce the NOARP mystery: 

ip link show eth0
/etc/rc.d/rc.eth eth0 stop
rm -rf /etc/fc/net/if/eth/eth0/link/ccrypt
/etc/rc.d/rc.eth eth0 start
ip link show eth0

A flatconf directory shouldn't vanish under normal circumstances. However, unwise pkg upgrades and filesystem corruptions happen. We don't want to have ip link arp off then. Do we?
