https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236949 Bug ID: 236949 Summary: Attempt to provide a boot profile manager Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: phascolarctos@protonmail.ch Created attachment 203310 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D203310&action= =3Dedit boot profile manager rc script At the moment, as far as I know, it is not possible in FreeBSD to have different profiles to select services at startup. For example, I can not de= cide at boot time to start netif on my laptop if and only if I have access to a connection: my choices are to always start it at boot or to always start it= by hand after boot. My rc script aims to give users choice at boot time. The service is called "boot_profile_manager" and is of course activated by setting boot_profile_manager=3D"YES" into rc.conf (but do not use rc.conf.d= : see later). The script should be the first service started on the system: I tried to de= fine this condition by setting "BEFORE: systcl". At boot time it will print a numbered list of profiles given by the variable $boot_profile_manager_profi= les that must be defined in rc.conf -- e.g, if boot_profile_manager=3D"default no_network testing", the menu will be: 1. default 2. no_network 3. testing To each profile must correpond a directory into /usr/local/etc/boot_profile_manager. Thus in the example we will have the directories /usr/local/etc/boot_profile_manager/default, /usr/local/etc/boot_profile_manager/no_network and /usr/local/etc/boot_profile_manager/testing. When user selects a profile, /etc/rc.conf.d becomes a symlink to the direct= ory of the selected profile. Thus if user selects profile 2 of our example, then /etc/rc.conf.d will be a symlink to /usr/local/etc/boot_profile_manager/no_network. (To be able to make the symlink, / is temporarly mounted rw and then restor= ed read-only.) A timeout is set by default to 5 seconds in case user does not select any profile and can be set to any value through "boot_profile_manager_timeout" variable: after the timeout, profile 1 is selected by default. That way users can put in /etc/rc.conf any configuration common to all prof= iles (e.g. hostname) and use directories into /usr/local/etc/boot_profile_manage= r as choices for /etc/rc.conf.d. I have tested successfully my script in a virtual machine running 13.0-CURR= ENT r345444 through bhyve and in my own system running 12.0-STABLE r345758. I think it would be nice to include this service into base system, but feel free to ask me to make a port of it if it would be preferable. Of course, I will be glad to make any modification required to meet standar= ds, improve quality etc. and I will write a manpage once the final version will= be ready. --=20 You are receiving this mail because: You are the assignee for the bug.=
