ASP asks me if I want to persist my already configured ASP

Once logged in and once my ASP have been installed, I get a notification asking me if I want to persist some of them.

======= content of /live/persistence/TailsData_unlocked/live-additional-software.conf =======
backupninja
freeipmi-tools
libdata-dumper-concise-perl
libtemplate-perl
libyaml-tiny-perl
make
rdiff-backup
ssmtp

And then:
