For example, with real systemctl, these commands will work correctly to create instances of `example@.service`: ```sh systemctl enable example@host.domain.com.service systemctl enable example@two\x2dwords.service ``` The former will run the service with the unescaped instance (`%I` in the unit file) set to `host.domain.com` and the latter as `two words`. The systemctl wrapper script is unable to parse these correctly. The former will be split on the first period, rather than the last, and try to create the instance `host` of `example@.domain.com.service`. The latter will try to unescape `\x2d` in the Python script and throw an exception. 103825 1 5170 trent.piepho 2026-01-13 03:41:34 +0000 Created attachment 5170 Proposed fix 103914 2 randy.macleod 2026-01-15 15:37:16 +0000 Hi Trent, Can you send the patch to the oe-core list? FYI: https://docs.yoctoproject.org/contributor-guide/index.html 103918 3 ross.burton 2026-01-15 15:39:58 +0000 Note that this won't be required for master/whinlatter/walnascar, as they have removed the replacement script from systemd-systemctl-native (oe-core 7a580800db ("systemd: Build the systemctl executable")) Also, a related patch would be "systemd.bbclass: support template files with dots". 104405 4 paul 2026-02-26 15:06:50 +0000 Hi Trent, Please re-submit the patch against the appropriate branch (scarthgap and/or kirkstone). As Ross says, this isn't required on walnascar or later and as Antonin says, the patch doesn't apply to the master branch [1].
