(v1.20.0) scheduler job using alpine cause standard_init_linux.go:190: exec user process caused "no such file or directory"

[llitfkitfk]

Bug description

docker run \
-v /:/host:ro \
-v /etc:/etc:ro \
-v /usr:/usr:ro \
-v /run:/run:ro \
-v /sbin:/sbin:ro \
-v /var:/var:ro \
-ti alpine sh /tmp/script.sh
standard_init_linux.go:190: exec user process caused "no such file or directory"

Expected behavior

docker run \
-v /:/host:ro \
-v /etc:/etc:ro \
-v /usr:/usr:ro \
-v /run:/run:ro \
-v /sbin:/sbin:ro \
-v /var:/var:ro \
-ti alpine sh /tmp/script.sh
sh: can't open '/tmp/script.sh': No such file or directory

Possible bugfix:
remove

-v /usr:/usr:ro

or leave user config

Right now we deliberately bind mount all these volumes from the host but we have in mind to enhance the UI/UX to give the user the ability to select which mounts he wants to bind mount for the job to run (e.g a list of checkboxes).
