Subject: [PATCH] blscfg: add a space char when appending fields for variable
|
|
expansion
|
|
|
|
The GRUB variables are expanded and replaced by their values before adding
|
|
menu entries, but they didn't include space characters after the values so
|
|
the result was not correct.
|
|
|
|
For the common case this wasn't a problem but it is if there are variables
|
|
that are part of the values of other variables.
|
