[CRIU] [PATCH 1/2] scripts: detect EOF on read in a usual way in systemd-autofs-restart.sh

[Eugene Kolomeetz]

When read bultin detects EOF, it sets empty string as value of specified
variable, and returns non-zero exit code. So we can rely just on exit
code, and not check variable value. This is standard approach.
