$(realpath /dev/shm) will return the absolute path of the target of
/dev/shm, thus the command will work for both absolute symlink and
relative symlink.
Some host create /dev/shm as a tmpfs. Some have is as
a symlink to a location in another directory. This
change handles both cases.
The change to the sysV bootscripts now creates /dev/shm
as a separate tmpfs from /run. This makes LFS sysV and
systemd versions treat /dev/shm the same.
- Use <emphasis role="bold"> for bold, instead of <command>.
- Remove "X window" as some graphical environments are Wayland-based.
- "Full BLFS" -> "BLFS", and "partial BLFS" -> "basic LFS" (I guess some
content is copied from Basic BLFS).
