"An alist of packages that are pinned to a specific archive
"An alist of packages that are pinned to specific archives.
This can be useful if you have multiple package archives enabled,
and want to control which archive a given package gets installed from.
Each element has the form (SYM . ID).
SYM is a package, as a symbol.
ID is an archive name. This should correspond to an
entry in `package-archives'.
Each element of the alist has the form (PACKAGE . ARCHIVE), where:
PACKAGE is a symbol representing a package
ARCHIVE is a string representing an archive (it should be the car of
an element in `package-archives', e.g. \"gnu\").
If the archive of name ID does not contain the package SYM, no
other location will be considered, which will make the
package unavailable."
Adding an entry to this variable means that only ARCHIVE will be
considered as a source for PACKAGE. If other archives provide PACKAGE,
they are ignored (for this package). If ARCHIVE does not contain PACKAGE,
the package will be unavailable."

;; I don't really see why this is risky...
