Can I break into this thread? I have a wagon load of heyu related scripts
I run here, controlling outside lighting etc. Under FC2, they run just
fine. But booted to FC6, all I can get out of tracing things is that it
cannot open /dev/ttyS1, so the whole thing falls over.
selinux is set permissive, and an ls -l of /dev/ttyS* show this:
crw-rw---- 1 root uucp 4, 64 Nov 9 16:35 /dev/ttyS0
crw------- 1 root root 4, 65 Nov 9 16:35 /dev/ttyS1
crw------- 1 root root 4, 66 Nov 9 16:35 /dev/ttyS2
crw------- 1 root root 4, 67 Nov 9 16:35 /dev/ttyS3
And the heyu stuff is running as root.
What else can I check & possibly adjust?
