Branch: refs/heads/master Home: https://github.com/tribe29/checkmk Commit: abce1d08f334aa892cfba48a7e702df7c1fa7373 https://github.com/tribe29/checkmk/commit/abce1d08f334aa892cfba48a7e702df7c… Author: Mathias Laurin <mathias.laurin(a)tribe29.com> Date: 2021-10-29 (Fri, 29 Oct 2021) Changed paths: M omd/packages/mk-livestatus/LIVESTATUS_TCP_ONLY_FROM M omd/packages/mk-livestatus/LIVESTATUS_TCP_PORT Log Message: ----------- LIVESTATUS_TCP_* substitute with ed instead of perl `perl -i` and `sed -i` are not true in place in that the original file gets unlinked and replaced. This is bad because the local configuration under `.config/systemd/user/` is hard linked to the template in `/etc/mk-livestatus`. And the hard linking is necessary because systemd tends to remove soft links. `ed(1)`, however, makes true in place edits that leave the inode unchanged. This is the only way to make the hard linking work as expected. An alternative could be `sponge(1)` that could let us keep perl but it *does not guarantee* that there will never be a copy. Anyway, the replacements are simple-enough that `ed(1)` is fine. CMK-8683 Change-Id: I95a0bf20278410e69475f46b2d05e4ad0c20c40b
