It appears that when we import github.com/coreos/go-systemd/activation, it brings in the whole crypto/tls package (which is not used by runc directly or indirectly), making the runc binary size larger and potentially creating issues with FIPS compliance. Let's copy the code of function we use from go-systemd/activation to avoid that. The space savings are: $ size runc.before runc.after text data bss dec hex filename 7101084 5049593 271560 12422237 bd8c5d runc.before 6508796 4623281 229128 11361205 ad5bb5 runc.after Reported-by: Dimitri John Ledkov <dimitri.ledkov@surgut.co.uk> Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
Remove unused code and argument from the ActivationFiles, and simplify its usage. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
