Unless we search the entire filesystem to do a chown *and* restart
existing processes owned by that user, there is no sensible way that
we can change uids/gids. So don't try.
The option is disabled by default so that previously existing installations
aren't affected.
If you'd like to migrate to the fixed numeric id for Apache, set "fixUidAndGid
= true", edit the file "/etc/groups" and replace the old GID value with 54.
(NixOS can't do that for you because it refuses to change a GID that identifies
the primary group of a user.) Then run
find / -xdev -uid $oldUID -exec chown 54 {} +
find / -xdev -gid $oldGID -exec chgrp 54 {} +
to update ownership of all files that are supposed to be owned by Apache.
GRUB 2 doesn't want to boot off a LVM disk:
machine# installing the GRUB 2 boot loader on /dev/vda...
machine# Path `/boot/grub' is not readable by GRUB on boot. Installation is impossible. Aborting.
machine# /nix/store/7yc535h1lim1a5gkhjb3fr6c8193dv8w-install-grub.pl: installation of GRUB on /dev/vda failed
In theory GRUB 2 supports booting from LVM, but we probably need to
generate the right grub.conf (see
https://wiki.archlinux.org/index.php/GRUB2#LVM).
http://hydra.nixos.org/build/2904680
- Renamed system.build.menuBuilder to system.build.installBootLoader.
- ‘install-grub.pl’ (formerly grub-menu-builder.pl) now generates the
GRUB menu *and* installs GRUB (if necessary).
- ‘switch-to-configuration.sh’ has no boot loader specific knowledge
anymore. It just calls installBootLoader.
The old GRUB menu builder script is quite slow, typically taking
several seconds. This is a real annoyance since it's run every time
you switch to a new configuration. Therefore this patch replaces the
Bash script with a much faster Perl script. In a VirtualBox test, the
execution time went from 2.7s to 0.1s. The Perl version is also more
correct because it uses XML to get the GRUB configuration (through
builtins.toXML), so there are no shell escaping issues.
The new script currently lacks support for subconfigurations defined
through "nesting.children".
