I have some comments about the manual [1] and questions about Guix
itself.

1. Can we change quotes?

  "Although GNU programs traditionally used 0x60 (‘`’) for opening and
   0x27 (‘'’) for closing quotes, nowadays quotes ‘`like this'’ are
   typically rendered asymmetrically, so quoting ‘"like this"’ or
   ‘'like this'’ typically looks better." [2]

2. "The build procedure for Guix is the same as for other GNU
   software, and are not covered here." [1]

   I think that it would be better to change it like this: "The build
   procedure for Guix is the same as for other GNU software and it is not
   covered here."

3. Could anyone add more about these?

  `--disable-log-compression'
       Disable compression of the build logs.

  `--disable-store-optimization'
       Disable automatic file "deduplication" in the store.

   Do compression and optimization have any disadvantages?

4. "as a unprivileged user" [1] should be changed to "as an
   unprivileged user."

5. Will it be possible to change 'guix-daemon' to run without root
   privileges and also catch impurities?

   I read the corresponding section.  Does it describe the current
   state of Guix or the limitations of the GNU system?

6. "By default, `guix-daemon' launches build processes under different
   UIDs, taken from the build group specified with
   `--build-users-group'.  In addition, each build process is run in a
   chroot environment that only contains the subset of the store that
   the build process depends on, as specified by its derivation (*note
   derivation: Programming Interface.), plus a set of specific system
   directories." [1]

   I guess that "runs" should be used instead of "is run."

7. "The command provides the obvious install, remove, and upgrade
   operations.  Each invocation is actually a _transaction_: either the
   specified operation succeeds, or nothing happens.  Thus, if the
   `guix-package' processed is terminated during the transaction, or if a
   power outage occurs during the transaction, then the user's profile
   remains in its previous state, and remains usable." [1]

   Will it be possible to resume the terminated transaction later?
   It's useful if you have a bad connection.

8. "The `guix-gc' command has three modes of operations: it can be
   used [...]" [1]

   It would be better to remove "of operations."

9. What is the difference between 'guix-build' and 'guix-package -i'?
   And why do we need both?

   'guix-package -i' creates a new profile, right?
