However, when built as part of rescue(8), getprogname doesn't work. It always returns the same name, regardless of how the binary was invoked. For example: > /rescue/fsck_ffs --help fsck_ffs: illegal option -- - usage: /rescue/iscsid [-BCdEFfnpRrSyZ] [-b block] [-c level] [-m mode] filesystem ... Notice that the usage string contains "/rescue/iscsid", which is obviously = not correct. --=20 You are receiving this mail because: You are the assignee for the bug.=
