This will block installing the package if the kernel is invalid, but |
26 |
will not block installing an invalid kernel later. Also, this needs |
27 |
to be done in an appropriate phase. |

You probably want to use a blocker for something like this, though |
30 |
portage doesn't always handle these well, and kernels are also a bit |
31 |
different as packages go. A blocker is just a dependency with an ! |
32 |
operator. Note that this blocks installing that kernel package, not |
33 |
running that kernel, which is why kernel dependences tend to be |
34 |
expressed differently. |

Personally, in situations where I'm very dependent on kernel series I |
37 |
just run upstream kernels. Gentoo barely patches its kernels so |
38 |
unless you REALLY need the gentoo patches it is pretty trivial to just |
39 |
sync from the stable repo and pull the appropriate branch for a |
40 |
longterm series. I do this for zfs, and have done it in the past for |
41 |
btrfs, and would do this anytime I needed to pin a particular kernel |
42 |
series. You would lose the benefit of any Gentoo QA, but IMO that |
43 |
benefits you mainly to the degree that you run typical packages, and |
44 |
you're already deviating from the script. |
45 |
|
46 |
If your package is in-tree and depends on kernel version you could |
47 |
file a bug to address this in some way. If it is in an overlay then |
48 |
you're on your own. |
