<title>Installation of Ed</title>
|
|
|
|
<note><para>Ed isn't something which many people use. It's installed here
|
|
because it can be used by the patch program if you encounter an ed-based patch
|
|
file. This happens rarely because diff-based patches are preferred these
|
|
days.</para></note>
|
|
|
|
<para>Ed uses mktemp to create temporary files in <filename
|
|
class="directory">/tmp</filename>, but this function has a security
|
|
vulnerability (see section on Temporary Files in <ulink
|
|
url="http://en.tldp.org/HOWTO/Secure-Programs-HOWTO/avoid-race.html"/>). This
|
|
patch makes Ed use mkstemp instead, which is the recommended way to create
|
|
temporary files.</para>

<para>We need to move the Ed binaries to the <filename

class="directory">/bin</filename> directory so they may be used in the event

that the <filename class="directory">/usr</filename> partition is

|
unavailable.</para>
