Bug ID: 230621
Summary: rc.subr wrong override for $command
Product: Base System
Version: 11.1-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: misc
Assignee: b...@freebsd.org
Reporter: eu...@freebsd.org
CC: do...@freebsd.org, port...@freebsd.org
/etc/rc.subr has run_rc_command() function used with base system and ports. The
function contains this code:
eval _override_command=\$${name}_program
command=${_override_command:-$command}
This code supposes that ${name} contents must have correct syntax for shell
variable. This is wrong for our Ports Collection having plenty of ports with
dash (-) in the ${name}. For such a port, ${name}_program expands to something
like: part1-part2_program with non-existing (empty) $part1 variable.
So, _override_command ends up with always-non-empty wrong value
"-part2_program". Therefore, the value of ${command} set by port's startup
script is always ignored due to code cited above and replaced with bad
"-part2_program" string that break it all.
