I'm unable to comment in direct comments, at StackExchange reputation 21. I just wanted to mention that the FreeBSD kernel does implement something like an I/O scheduler, namely gsched. Reviewing the manual page, it seems to be a device-specific IO scheduler. Personally, I think it's a nice keynote toward realtime applications of FreeBSD, and a great reason ...

Sometimes a single heavy I/O operation may affect kernel performance with respect to all I/O taks, including those not directly operating on the device of the first one. The first and indirect way to control priorities on I/O scheduling is the tuning of process' nice level you already mentioned. In modern Linuxes, a process with a nice value of 19 (i.e., ...

That's quite straightforward. Type one of these commands pkg install gnome2 pkg install x11/kde4 pkg install xfce depending whether you would like to have GNOME, KDE or Xfce as your desktop environment. For more info, read the guide.

There isn't yet official package repository to RPI so you can't install any official program yet. There is an unofficial repository for ARM (and FreeBSD 11) here but it seems it's empty. I'm maintaning a small repository too but for FreeBSD 10.x - see here.

If you use acls, the classic group permissions turn into the so called mask,which determines the maximum permissions you can effectivly give per setfacl, eg. ls -k shows -rw-r--r--+ root root and you have setfacl -m g:users:rw because the mask is only read getfacl will show you : group:users:rw effective r So set group to rw or rwx by classic chmod and ...

FreeBSD doesn't have an equivalent. The convention is not to use group passwords at all and just put an asterisk in the password field. No group passwords means no need to have something like /etc/gshadow.

Ok I figured It out I needed to run pkg install php56-[missng module name]-5.6.9 For each of the above modules (in fact hash came with one of the others) I also ran pkg install OpenSSL but I'm not sure if I needed to go that or not.

From the manpage of the syscall chflags(2): SF_IMMUTABLE The file may not be changed. SF_NOUNLINK The file may not be renamed or deleted. [...] UF_IMMUTABLE The file may not be changed. UF_NOUNLINK The file may not be renamed or deleted. The flags prefixing with SF_ may only be set or unset by the super-user. The others prefixing with UF_ may ...

I had a similar issue on FreeNAS 9.3 and could not find a remove button. I got it to disappear by going to the jails volume, and removing the directory which held the jail: # rm -fr /mnt/black/jails/.couchpotato_1.meta/ This also removed the complaints during boot. No negative side effects seen yet.

So far as research, there's a couple of projects managed at the Centre for Advanced Internet Architectures (CAIA) at the University of Swinburne. They've been focusing at least partly about delay-based algorithms in FreeBSD[newtcp]. Together with the support of the FreeBSD foundation, the newtcp project's work has been integrated with FreeBSD 9.0 and ...

You should be able to set the kern.vt.fb.default_mode sysctl. See the vt man page for more details.
