The --capabilities flag allows you to control the dropping of capabilities during execution time or set specific capabilities.
Possible options:
bypass=[true|false]: Keep all capabilities during execution time. Setting bypass=true will opt out from dropping any capabilities.
add=cap1(,cap2...): Add specific capabilities to the "required" capabilities ring. You can provide multiple capability names separated by commas.
drop=cap1(,cap2...): Drop specific capabilities from the "required" capabilities ring. You can specify multiple capability names separated by commas.
Please note that the available capabilities will depend on the running system. For the list of capabilities available on your system, see the list-caps command.
