Sleep in cryptroot-unlock specified in fractions of a second

[Peter Glock]

I'm using cryptroot-unlock for remote unlocking of a LUKS partition for secure booting of a raspberry pi.

The script works fine in that I can enter an unlock code and continue with boot, but before boot continues I see an error message of "Error: Timeout reached while waiting for PID".

I've traced the issue to /usr/share/cryptsetup/initramfs/bin/cryptroot-unlock

On line 86, I see "sleep .1"

In the version of Busybox used on the Pi, sleep can only be specified in whole seconds.

Changing ".1" to "1" makes the script exit normally with no errors.

Checked on BusyBox 1.1.2 which DOES allow fractional sleep durations. Please ignore this report.
