Hi,
in case someone also has the desire to be able to turn the syscons
CTRL-ALT-DELETE Reboot on and off without a kernel re-compile,
this patch is for you.
It adds a sysctl variable named : hw.syscons.pc_style_reboot
which enables (>0) or disables (0) reboot using CTRL-ALT-DELETE.
The setting can also be added to /boot/loader.conf as in :
hw.syscons.pc_style_reboot="0" # Disable CTRL-ALT-DEL Reboot
Guess it would be nice to have this in the official sources.
The provided diff is against RELENG_4 as of 4.8.2001 - or
src/sys/dev/syscons/syscons.c,v 1.336.2.10.
It should work for -current as well as pc98/pc98/syscons.c, although
I have not verified that.
Possible <freebsd-hackers@FreeBSD.ORG> would be the place for this
- but I haven't subscribed there (yet) - let me know.
Regards,
Pascal
