[systemd-devel] systemctl show environment quoting

[Alexandre Detiste]

Hi,

I stumbled on this:

$ systemctl cat cron-crontab-pi-0 | grep Environment
Environment="A=a a" "MAILTO=system-cron at mailinator.com" "B=b b" "C=c c"
$ systemctl show cron-crontab-pi-0 -p Environment
Environment=A=a a MAILTO=system-cron at mailinator.com B=b b C=c c

-> the quotes are gone.

Is this done by design, or a bug in "systemctl show" ?

My simple parser could be abused if someone hid a MAILTO= inside an other env variable.

Here this won't hurt, but this may causes security problems elsewhere.
