The old attribute is deprecated:
trace: warning: In test `chromium-stable': The `machine' attribute in NixOS
tests (pkgs.nixosTest / make-test-pyton.nix / testing-python.nix / makeTest) is
deprecated. Please use the equivalent `nodes.machine'.
Note: This is only a refactoring.
This should be a significant disk space saving for most NixOS
installations. This method is a bit more complicated than doing it in
the postInstall for the firmware derivations, but this way it's
automatic, so each firmware package doesn't have to separately
implement its compression.
Currently, only xz compression is supported, but it's likely that
future versions of Linux will additionally support zstd, so I've
written the code in such a way that it would be very easy to implement
zstd compression for those kernels when they arrive, falling back to
xz for older (current) kernels.
I chose the highest possible level of compression (xz -9) because even
at this level, decompression time is negligible. Here's how long it took
to decompress every firmware file my laptop uses:
i915/kbl_dmc_ver1_04.bin 2ms
regulatory.db 4ms
regulatory.db.p7s 3ms
iwlwifi-7265D-29.ucode 62ms
9d71-GOOGLE-EVEMAX-0-tplg.bin 22ms
intel/dsp_fw_kbl.bin 65ms
dsp_lib_dsm_core_spt_release.bin 6ms
intel/ibt-hw-37.8.10-fw-22.50.19.14.f.bseq 7ms
And since booting NixOS is a parallel process, it's unlikely (but
difficult to measure) that the time to user interaction was held up at
all by most of these.
Fixes (partially?) #148197
These two packages don't have a lib/firmware directory, so putting
them in hardware.firmware has no effect. This will become a hard
error once firmware compression is implemented.
(In the case of Linux, the firmware was all moved to linux-firmware.)
automysqldump passes the --events flag, but without the EVENTS permission a error occures:
> mysqldump: Couldn't execute 'show events': Access denied for user 'automysqlbackup'@'localhost' to database 'mysql' (1044)
Add support for enabling confinement
but does not enable it by default yet
because so far no module within NixOS uses confinement
hence that would set a precedent.
