Subject: [PATCH] cryptsetup: don't add unit dependency on /dev/null devices
|
||
|
|
when it is listed as password file
|
||
|
|
|
||
|
|
As special magic, don't create device dependencies for /dev/null. Of
|
||
|
|
course, there might be similar devices we might want to include, but
|
||
|
|
given that none of them really make sense to specify as password source
|
||
|
|
there's really no point in checking for anything else here.
