I have an issue regarding kernel relinking during upgrade. Not a big chunk, but I prefer to report it to see the better way to change my workflow or to change operations order in installer. I use /upgrade.site file in order to patch in advance (from the installer, and before rebooting) the kernel in order to disable ulpt to let cups using my usb printer using libusb. # cat /upgrade.site #!/bin/sh PATH=/sbin:/bin:/usr/sbin:/usr/bin # disable ulpt if cupsd installed [[ -x /etc/rc.d/cupsd ]] && echo 'disable ulpt*\nquit' | config -f -e /bsd.mp exit 0 The current order of operation in the installer is (after manual inspection): - do install/upgrade stuff - run /$MODE.site in chroot (here upgrade.site) - MAKEDEV and installboot - bsd.mp renaming to bsd if MULTIPROCESS - KARL stuff - generating sha256 from /bsd - relinking to create an unique kernel - adding sysmerge and fw_update in rc.* files - few other stuff and rebooting The interaction between /upgrade.site (patching /bsd) and KARL makes the reconfiguration stuff to be discarded... and my printers to not be functional using libusb at reboot (due to ulpt). Some questions/options: - should /$MODE.site to ran a bit later ? (after KARL) - should /$MODE.site to ran after "generating sha256 from /bsd" and before "relinking to create an unique kernel" ? it should let "make newbsd" detect /bsd modification, and not relinking the kernel. - what is the expected way to disable KARL in the installer ? (I assume removing /usr/share/compile.tgz and /usr/share/compile should be enough) - does patch for something like config(8) script would be acceptable, in order to have an official way to apply config(8) modification *and* to have KARL at same time ? For me, patching the kernel in rc.firsttime wouldn't be a great option: it will require a reboot to apply settings. Thanks. -- Sebastien Marie
