5.7+ comes with a native exfat implementation, exfatprogs should be used instead.
The exfat package puts a "mount.exfat" binary in the path, which causes
mount to prefer the FUSE version to the non-fuse one. There's no way to
disable the binary, so switch to exfatprogs.
This should barely increase the size of the initrd, because these are all symlinks.
With this, systems with dm-cache/lvmcache can also be booted, although the kernel modules for the relevant dm targets still need to be added to the initrd with boot.initrd.kernelModules.
If the pstore module is builtin, it nonetheless can take considerable
time to register a backend despite /sys/fs/pstore already appearing
mounted, so the condition is moved into the main script to extend
waiting for the backend to this case.
systemd's modprobe@.service does not require success so mount-pstore
executed despite a non-present pstore module, leading to an error about
the /sys/fs/pstore mountpoint not existing on CONFIG_PSTORE=n systems.
According to fstab(5), unlike last two fields `fs_freq` and `fs_passno`,
the 4-th field `fs_mntops` is NOT optional, though it works when omitted.
For best-practice and easier to be parsed by other programs, we should always
write `defaults` as default mount options for swap devices.
The `networking.hostname` option was changed to not permit periods
in names, due to a strict reading of RFC 1123. For users who need
the hostname to be fully qualified, the networking.hostName option
suggests using boot.kernel.sysctl."kernel.hostname" as a workaround.
This option works correctly at boot time, but every "nixos-rebuild
switch" will change the hostname back to the unqualified version.
This commit brings the activation script in line with the
documentation's recommendation.
This reverts commit d349582c07.
The workaround initially applied isn't necessary anymore, as 247.3
contains the following commit:
> 242fc1d261 network: fix IPv6PrivacyExtensions=kernel handling
… which fixes https://github.com/systemd/systemd/issues/18003.
If the machine is powered off when the zpool-trim timer is supposed to
trigger (usually around midnight) then the timer will be skipped
outright in favor of the next instance.
For desktop systems which are usually powered off at this time, zpool
trimming will never be run which can degrade SSD performance.
By marking the timer as `Persistent = yes` we ensure that it will run at
the first possible opportunity after the trigger date is reached.
