The new initscript is broken: @SBINDIR@/@IPSEC_SCRIPT@ in exec is not
replaced correctly with /usr/sbin/strongswan * 1069928 is not fixed. I am
still seeing the /usr/bin/pki errors when calling 'strongswan pki' * Calling
/usr/libexec/strongswan/pki directly seems work correctly now
4.11.x breaks ipsec connections (due to esp4 bug): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0e78a87306a6f55b1c7bbafad1de62c3975953ca
