Subject: [PATCH] groupdel: fix SIGSEGV when passwd does not exist
|
|
|
|
When using groupdel with a prefix, groupdel will attempt to read a
|
|
passwd file to look for any user in the group. When the file does not
|
|
exist it cores with segmentation fault.
|
|
|

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1986111
|
|
Conflict: context adaptation
