Hello, |
| 2 |
|
| 3 |
I am using umask 027 on my Gentoo boxes, and setgid bit set on a few |
| 4 |
directories crucial to userpriv-enabled merges. This way, I do not have |
| 5 |
to worry about running e.g. layman through 'sg' or similar tools, as |
| 6 |
all newly-created files inherit portage group ownership, and |
| 7 |
newly-created directories inherit the setgid bit. |
| 8 |
|
| 9 |
I would like to be able to use similar solution for compiled kernel |
| 10 |
sources, i.e. through setting the setgid bit on /usr/src. But in fact |
| 11 |
it is impossible as portage forces setting it's own permissions on all |
| 12 |
installed files, thus newly-installed kernel sources do not inherit the |
| 13 |
parent group ownership nor the setgid bit. |
| 14 |
|
| 15 |
Now the question is: should such behaviour be considered really correct |
| 16 |
and necessary? In my opinion, if user sets setuid/setgid on a parent |
| 17 |
directory, shklee knows what shklee is doing and emerge should not |
| 18 |
override this system-specific ownership inheritance. |
