Subject: Allow disabling seccomp or changing the whitelist
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e29966f04cdf549a01f721f93634672055da8af4;p=oweals%2Fprocd.git

Allow disabling seccomp or changing the whitelist

Without this change, once a service is started with seccomp, it is
impossible to restart it without seccomp or change the whitelist file
name. This commit fixes that. Disabling seccomp is as easy as
commenting out the "procd_set_param seccomp" line in init.d script.
