Bug ID: 251409
Summary: getprogname(3) does not work for rescue binaries
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
Some utilities (e.g. reboot, ping, fsck_ffs) install multiple hard links and
use getprogname(3) to tell which was invoked, triggering different behavior
based on the name of the invoked link. 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.
