ssh-agent as a wrapper program for
startx. Is it a security risk, to use always the same socket file?
ssh-agent -a /tmp/xyz123 startx
-a specifies the socket bind address. If not specified, it would be a random filename.
I'd like to use a fix socket filename because I want to specify
SSH_AUTH_SOCK=/tmp/xyz123 in my crontab file. Otherwise cronjobs that use SSH fail.
