New thin laptops don't have an ethernet port and so rely on wifi to get
access. With the minimal installer, setup wpa_supplicant can be hard if
it is the first time so here we provide an example.
This was only applicable to very specific hardware, and the only person
with an apparent interest in maintaining it (me) no longer uses the
hardware in question.
"Ejecting" from the Finder ejects the entire device which is then not available for dd. diskutil unmountDisk does the right thing. Furthermore writing to diskN instead of rdiskN failed to complete even after waiting >10 minutes.
before:
- /var/run/memcached is a bad default for a socket path, since its
parent directory must be writeable by memcached.
- Socket directory was not created by the module itself -> this was
left as a burden to the user?
- Having a static uid with a dynamic user name is not very useful.
after:
- Replace services.memcached.socket by a boolean flag. This simplifies
our code, since we do not have to check if the user specifies a
path with a parent directory that should be owned by memcached
(/run/memcached/memcached.sock -> /run/memcached).
- Remove fixed uid/gid allocation. The only file ever owned by the
daemon is the socket that will be recreated on every start.
Therefore user and group ids do not need to be static.
- only create the memcached user, if the user has not specified a
different one. The major use case for changing option is to allow
existing services (such as php-fpm) opening the local unix socket.
If we would unconditionally create a user that option would be
useless.
This allows one to specify "related packages" in NixOS that get rendered into
the configuration.nix(5) man page. The interface philosophy is pretty much
stolen from TeX bibliography.
Changed extraUsers -> users and one case of extraGroups -> groups in nixos manual chapter 7.
According to chatter on IRC these are the proper names for these configuration options nowadays.
Modified based on feedback from Jörg Talheim.
Previously only the line numbers of a giant, internally generated XML file were
printed, without any kind of debuggability.
Now at least the mentioned lines are printed with a little bit of surrounding
context (to have something to grep for).

Since ssh-dss is no longer supported by default, users relying on those
keys for their login may be locked out. They should ideally use stronger
keys, but adding the support for ssh-dss back in can also be done
through extraConfig.
