- add /etc/os-release

remove hostname from /etc/issue, it is printed by login
use softdeps rather than install hacks for usb modules
don't hardcode paths in install scripts (fixing grep usage)
remove .KEEP file

install symlinks from /var/{run,lock} to /run/{,lock}
use softdeps in order to load usb modules in the right order

I was a bit too optimistic thinking we would not need a new filesystem release before
pacman 4.

Mounting /tmp as noexec is recommended by some guidelines, and it probably defends against some attacks. However, some packages rely on /tmp being mounted exec, so we do that by default.

At the end of the day the admin decides the contents of fstab, so the default is not that important.

This is now done by default by agetty, and this behavior can be switched off using the --no-clear option. There is no need to duplicate the functionality in the issue file.

Packages should only install files in /lib, never in /etc.

/dev/{shm,pts} are dealt with by initrd or rc.sysinit.

Making /tmp a tmpfs by default as this is almost always
the right thing to do.

* Add missing quotes in /etc/profile (FS#22970)
* Add /run directory

See https://bugs.archlinux.org/task/21759

* Do it like Debian or Ubuntu and only source the global bashrc when running bash.
* Other shells like zsh have their own global config anyway.
* In fact sourcing the global shell config was only needed/used by bash.
* see https://bugs.archlinux.org/task/20288

* Higher level dirs override lower ones in PATH now

* Fix syntax error when using grep

See https://bugs.archlinux.org/task/21180

* This mountpoint are causing problems (see https://bugs.archlinux.org/task/20894)
* Those mount point are handled by DEs/automounters differently
* We shouldn't assume users have a floppy driver, cdrom and dvd drives. Most likely they don't.
