| - | === Note on ZFS === | ||
| - | ZFS at time of writing does not support encryption, so to use dm-crypt is still a good solution. But ZFS encrypted pools are already in the unstable code, so if doing an installation with ZFS double check if to use ZFS directly is already possible. | + | === Partitions inside the text-plain abstraction === |
| + | |||
| + | Once the text-plain abstraction is set up, the initcpio encrypt hook does not automatically look up for partitions inside. If needed, we can alter the encrypt hook and installation to call ''partprobe'' (package | ||
| + | ''parted'') to inform the OS of the new partitions. | ||
| + | |||
| + | In the hook file look up for lines with ''if [ -e "/dev/mapper/${cryptname}" ]; then'' two of those ifs check if the text-plain abstraction has been properly created. Just add ''partprobe -s "/dev/mapper/${cryptname}"'' in a line below (The ''-s'' option is not necessary, but to see the detected partitions can help debugging.) At time of writing the two lines are the 91st and the 129th. | ||
| + | |||
| + | Example: | ||
| + | 91 if [ -e "/dev/mapper/${cryptname}" ]; then | ||
| + | ... partprobe -s "/dev/mapper/${cryptname}" | ||
| + | 92 if [ ${DEPRECATED_CRYPT} -eq 1 ]; then | ||
| + | 93 export root="/dev/mapper/root" | ||
| + | 94 fi | ||
| + | 95 else | ||
| + | |||
| + | Partprobe is part of the package ''parted'' and the executable has to be added in initcpio image using the install file. In the install file, add in the ''build'' function a line with: | ||
| + | |||
| + | add_binary "partprobe" | ||
| + | |||
| + | To use ''partprobe'' in the encrypt hook allows to have a full-system encryption and still use partitions to keep data separated or to use an encrypted swap. | ||

| + | ====== Post-installation ====== | ||
| + | |||
| + | Once started the X (Wayland) server the font configuration will be horible. Often the spacing between the characters will be totally messed up. Here are the instructions to set up the fonts properly ([[https://www.reddit.com/r/archlinux/comments/5r5ep8/make_your_arch_fonts_beautiful_easily/|Original post]].) | ||
| + | |||
| + | First of all install the liberation fonts, it indirectly sets up the correct characters positions. | ||
| + | |||
| + | # pacman -S ttf-liberation | ||
| + | |||
| + | Secondly install a bit more fonts. | ||
| + | |||
| + | # pacman -S ttf-ibm-plex ttf-dejavu noto-fonts | ||
| + | |||
| + | Enable font presets: | ||
| + | |||
| + | # ln -s /etc/fonts/conf.avail/70-no-bitmaps.conf /etc/fonts/conf.d | ||
| + | # ln -s /etc/fonts/conf.avail/10-sub-pixel-rgb.conf /etc/fonts/conf.d | ||
| + | # ln -s /etc/fonts/conf.avail/11-lcdfilter-default.conf /etc/fonts/conf.d | ||
| + | |||
| + | In the ''/etc/profile.d/freetype2.sh'' file uncomment the ''FREETYPE_PROPERTIES'' line. | ||
| + | |||
| + | |||
| + | Finally create the ''/etc/fonts/local.conf'' file with the following content. The file tells the system what you mean with //serif//, //sans//, or //monospace//. | ||
| + | |||
| + | <?xml version="1.0"?> | ||
| + | <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> | ||
| + | <fontconfig> | ||
| + | <match> | ||
| + | <edit mode="prepend" name="family"><string>Liberation Sans</string></edit> | ||
