</div></div>/sbin/reboot is part of the sysvinit package on my distro.<br>
<br>
Why would the kernel build / install have anything to setting its permissions?<br>
<br>
If you are working with a typical Makefile process, permissions are<br>
set when you do a make install.<br>
<br>
If you are working with a rpm, then the specfile that created the rpm<br>
can either use the default "make install" permissions or it can<br>
control the process with as much detail as it wants. ie. The specfile<br>
has a install section which is basically just some shell script logic.<br>
<br>
If you want to see some specfiles, one of the easiest places to look<br>
is the openSUSE build service. (OBS). Every package has a specfile<br>
and they are all readily read through.<br>
<br>
The hard part is actually finding a simple enough one that it is easily read.<br>
<br>
I wrote this one for a very simple package a while ago, so it is<br>
pretty easy to read:<br>
<br>
<a href="https://build.opensuse.org/package/view_file?file=open2300.spec&package=open2300&project=hardware&srcmd5=e4de1aefeb524c520ce7d3882a709e60" target="_blank">https://build.opensuse.org/package/view_file?file=open2300.spec&package=open2300&project=hardware&srcmd5=e4de1aefeb524c520ce7d3882a709e60</a><br>
<br>
Note the "%defattr(644,root,root,755)" line. That is forcing some<br>
permissions, owners, etc.<br>
