Subject: [PATCH] install/dracut-install.c: Deal gracefully with paths
|
|
containing double /'s
|
|
|
|
While such paths should not be included internally, we cannot
|
|
guarantee that external scripts with shebangs will not do this.
|
|
|
|
Some older versions of plymouth also resulted in double /'s
|
|
in some paths, so best deal with this gracefully.
