Package: rng-tools Version: 2-unofficial-mt.14-1 Severity: wishlist Dear Maintainer,
rng-tools works in sysV compatibility mode. No native systemd .service file.
One problem is that the the sysV version uses bash computing to search
a list of random file names. I have created a bash file that does this
then execs rngd. I have tested this on my raspberry PI which runs
systemd version 44. Changes may be required to upgrade to current version.
