Re: FreeBSD Boot Times

That is a fairly common response. I would appreciate suggestions on how I can convey that OpenRC is a good init system. Also, I am certain that the OpenRC developers would be thrilled if FreeBSD adopted OpenRC. If FreeBSD core is interested in OpenRC, feel free to contact the OpenRC and/or the Gen

Linux does this by keeping a list of driver id's and corresponding driver modules. The installers can then generate of list of modules to load based on a scan done at install time. what a problem to compile custom kernel? ___ freebsd-hackers@freebsd.o

The OpenRC is sysvinit compatible, but it has few of sysvinit's flaws. It has named runlevels, the presence of an init script does not cause it to start and it is in my opinion a joy to use. I suggest that you try OpenRC before drawing conclusions. You can install Gentoo FreeBSD in a jail. There a

Greetings, I was just wondering what it is that FreeBSD does that makes it take so long to boot. Booting into Ubuntu minimal or my own custom Linux distro, literally takes 0.5-2 seconds to boot up to shell, where FreeBSD takes about 10-20 seconds. I'm not sure if anything could be parallelized

Re: FreeBSD Boot Times

They have a lot of manpower and can spend a lot of time replacing the boot subsystems and all startup scripts every 2 releases. For FreeBSD it's not a big issue as most people don't reboot often. If it's an itch you want to scratch you're more than welcome to look into it; that seems to be th
