I think the intention was to use "" for bits with substititions and '' for bits
without, but that makes it hard to read and the bits in '' are safe in the ""
context anyway.
Running:
./scripts/update-component-sha.sh --image linuxkit/runc 100d0d046c
Still DTRT and updates runc to that (bogus) sha.

$0 --<mode> <how-to-find> <new-hash>
|
|
|
|
Available modes: --hash and --image
|
|
|
|
Replace by hash:
|
|
$0 --hash <OLD> <NEW>
|
|
Example: $0 --hash 8675309abcdefg abcdef567899
|
|
Will replace all instances of 8675309abcdefg with abcdef567899
|
|
|
|
Replace by image: $0 --image <IMAGE> <NEW>
|
|
$0 --image <IMAGE> <NEW>
|
|
Example: $0 --image linuxkit/foo abcdef567899
|
|
Will tag all instances of linuxkit/foo with abcdef567899
|
|
|
|
$0 --image <IMAGE>:<NEW> is accepted as a convenient shortcut for cutting
|
|
and pasting e.g.the output of linuxkit pkg show-tag
|
|
|
|
By default, for convenience, if no mode is given (--image or --hash), the first method (--hash) is assumed.
|
|
Thus the following are equivalent:
|
|
$0 <OLD> <NEW>
|
|
$0 --hash <OLD> <NEW>
