Current Fedora packaging guidelines prohibit using tricks like #!/usr/bin/env perl, instead requiring #!/usr/bin/perl hardcoded paths for all scripts packaged and distributed with Fedora. In fact, the build process will fixup script shebang lines automatically. https://pagure.io/packaging-committee/issue/700 https://docs.fedoraproject.org/en-US/packaging-guidelines/#_shebang_lines ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

There is also iPXE which can boot over the Internet from a CD-ROM: http://ipxe.org/start And this, but I'm not sure it is being updated anymore: https://boot.fedoraproject.org/index ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org

No it does not have to be on the same subnet, nor does it need any special forwarding on the router. All you need is a couple DHCP options set on your DHCP server and a TFTP server anywhere on your network to hold the pxelinux.0 and vmlinuz/initrd images. > But then I have avoided PXE boot for a decade or more for the above reasons. You've been missing out. I love being able to boot today's rawhide without waiting for any media to burn. ___ test mailing list -- test@lists.fedoraproject.org To unsubscribe send an email to test-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@lists.fedoraproject.org
