@kemona_halftau according to this article I found it seems to be mostly british spelling but with some bits of american spelling (most of which aren’t universally agreed upon)
but that article is wrong about british oxford spelling (oxford spelling uses -ize, not -ise) so I’m not sure how much I trust it
@foxyloon btrfs raid-1 is stable and safe to use (unlike raid-5/6 which has the write hole and I wouldn’t trust), but there are several things to note:
degraded mount optionbtrfs balance to resync it and ensure everything is on both devices@foxyloon I use btrfs. It has the advantage over md-raid that it checksums data/metadata so if one copy gets corrupted btrfs scrub will be able to detect which device has the correct data and repair the other one.
To create a raid1 filesystem across multiple devices, use mkfs.btrfs -d raid1 -m raid1 /dev/device1 /dev/device1
To add a new device and convert existing filesystem to raid1 do btrfs device add /dev/device2 /mountpoint to add the new device followed by btrfs balance start -dconvert=raid1,soft -mconvert=raid1,soft /mountpoint to convert data and metadata to raid1
@kemona_halftau on the stock firmware you should use thinkpad_acpi but if you happen to be on coreboot on an thinkpad between ivybridge (3rd gen/xx3x) and kaby lake refresh (8th gen/xx8x) (maybe also earlier and later versions but I haven’t confirmed that, doesn’t work on X200) you can use ectool from coreboot:
# to set the charging start threshold to 50%
ectool -w 0xb0 -z 0x32
# to set the charging end threshold to 50%
ectool -w 0xb1 -z 0x32
@april I did look and found the text of the GPLv3 in LICENSE but didn’t find anything specifying it was GPLv3-or-later other than the commit message. The text of the GPL itself only says this:
If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation.
If you don’t specify “or any later version” somewhere, the default is the specified version only.
