Fixes#15512 and #16032
With the multi output, postgresql cannot find at runtime what is its
basedir when looking for libdir and pkglibdir. This commit fixes that.
Before this commit updating /var/setuid-wrappers/ folder introduced
a small window where NixOS activation scripts could be terminated
and resulted into empty /var/setuid-wrappers/ folder.
That's very unfortunate because one might lose sudo binary.
Instead we use two atomic operations mv and ln (as described in
https://axialcorps.com/2013/07/03/atomically-replacing-files-and-directories/)
to achieve atomicity.
Since /var/setuid-wrappers is not a directory anymore, tmpfs mountpoints
were removed in installation scripts and in boot process.
Tested:
- upgrade /var/setuid-wrappers/ from folder to a symlink
- make sure /run/setuid-wrappers-dirs/ legacy symlink is really deleted
Add code to accountsservice that returns an error if the environment
variable NIXOS_USERS_PURE is set. This variable is set from the nixos
accountsservice module if mutableUsers = false
Both btrfs-progs and utillinux are ~5MB, we may discuss in future
to handle this better but I see no better way at the moment than
increaing purity in the install process.
OnCalendar entrys can be specified multiple times in a systemd timer, to
make more complex scheduling possible.
Tested by manually checking the timer generated by the following:
systemd = {
services.huhu = {
description = "meh";
wantedBy = [ "default.target" ];
serviceConfig.ExecStart = "/bin/sh -c 'printf HUHU!'";
startAt = [ "*:*:0/30" "*:0/1:15" ];
};
};
It prints HUHU to the log at seconds 0, 15 and 30 of each minute.
This was one of the ways to build packages, we are trying
hard to minimize different ways so it's easier for newcomers
to learn only one way.
This also:
- removes texLive (old), fixes#14807
- removed upstream-updater, if that code is still used it should be in
separate repo
- changes a few packages like gitit/mit-scheme to use new texlive
Verified that following nixos configuration:
users.users.foo = {
uid = 1000;
name = "foo";
};
users.users.bar = {
name = "bar";
};
Before this commit both users will get uid of 1000, after it's applied
bar will correctly get 1001.
