IIUC "early-commands" are shell commands? If so, then just use the
shell command "if" ("test").

[rocketmouse at archlinux ~]$ test -e /dev/sdz1; echo $?
1
[rocketmouse at archlinux ~]$ test -e /dev/sda1; echo $?
0
[rocketmouse at archlinux ~]$ if [ -e /dev/sdz1 ]; then echo "mount && cp"; fi
[rocketmouse at archlinux ~]$ if [ -e /dev/sda1 ]; then echo "mount && cp"; fi
mount && cp
[rocketmouse at archlinux ~]$
