0bf6e572bd rc.d/linux: Attempt to mount only if necessary
Currently, if the linux service is run twice, mount(8) fails with:

    mount: linprocfs: Device busy
    mount: linsysfs: Device busy
    mount: devfs: Device busy
    mount: fdescfs: Device busy
    mount: tmpfs: Device busy

It is a bit more user-friendly if before running mount(8) the service
checks if there are any file systems left to be mounted. This patch
implements this behavior.

Also, while here, create mount points directories (as suggested by
otis).

2ffd6857cc rc: make the 'linux' script explicitly load filesystem modules
This removes a minor annoyance with Linux jails, where you often
want linux_mounts_enable="NO", yet you want those filesystems
available for mounting in jails; normally mount(8) would result
in kernel automatically loading the KLD, but this doesn't work
inside jails or chroots.

933cb282b6 Fix the 'linux' rc script on aarch64.
Previously it would try to load linux.ko instead of linux64.ko
and fail.  While here, don't try to match 'linuxaout'; even if
implemented, it's the same module as `linuxelf`.

5dc2e1bcf4 Don't check compat.linux.emul_path before loading linux(4)
Fix e40787f900 to make libexec/rc/rc.d/linux retrieve the sysctl
after loading the kernel module which provides it, not before.

1b2802ed4e Use compat.linux.emul_path instead of hardcoded path in /etc/rc.d/linux
In /etc/rc.d/linux the mounting paths of procfs, sysfs and devfs
are hardcoded to "/compat/linux".  Switching to the content of
compat.linux.emul_path sysctl would allow to switch linuxulator
to different place.

This fixes Linux gettyname(3), with caveats (see PR).

5dece9b25a Add 'linux_mounts_enable' rc.conf(5) variable, to make it possible
to disable mounting Linux-specific filesystems under /compat/linux
when 'linux_enable' is set to YES.

it's entirely linux-specific.
