Debconf code for getting usernames list

[Nikos Andrikos]

Hi,

I am the maintainer of the kismet package and on installation time I
need to ask for the user to specify which users should go in the
kismet group, which is used in order to avoid running kismet as root.
Currently [1] this is done like this :

addgroup --quiet --system $GROUP
db_get kismet/install-users
if [ "$RET" != "" ]; then
for x in ${RET}; do
usermod -a -G $GROUP $x
done
fi

My problem is that sometimes the users might specify a wrong list
(comma-separated instead of space-separated, a typo in the username,
etc). This means that the usermod command will fail and actually this
will be shown as an error (code 6) in the installation of the package.
What is the proper way to check that each member of the $RET list is a
valid username and if not prompt the user to specify a new correct
list?

Thanks in advance,

Nikos

Re: Copyright format “License” field: grant of license, license text?

[Nikos Andrikos]

Hi Ben,

I believe you can put this text in the Comment: field of the corresponding
entry in your debian/copyright.

Kind regards,
Nick
