[anonymous-bugs]

Hi,

Im trying to add my packages into the iso using make iso, but logs dont show them getting installed and they dont show up when booting up iso
Steps I followed

1. git clone
2. cd mfsbsd
3. mkdir packages
4. cp ~/mypack.pkg packages
5. make iso BASE=/mnt/usr/freebsd-dist

Found this in issues, Looks like this support was removed for some reason, But still exists in documentation
